When it comes to our mother tongue, most of us don’t give language a second thought. However, without language, almost all aspects of life as we know it would break down. Teaching foreign languages gives others access to a completely fresh perspective on human life, as seen through the lens of a new language. With today’s growing rate of globalization, starting a foreign language instruction business can offer you an exciting and profitable career.
If you can attract a regular audience for your podcast, there’s good money to be made from sponsorships and other digital product offerings. At my own day job, we regularly pay $250 to $500 for 30-second advertisements on relevant business podcasts. Check out this episode of the Conscious Millionaire Podcast for an interview with John Lee Dumas, the host of Entrepreneur on Fire, for more tips on how to make money podcasting, including selling online courses, eBooks, and coaching sessions.

16 Be a doula Jasmine Birtles, the founder of website moneymagpie.com, says you can make between £12 and £15 an hour or £250-£500 for a birth by being a doula – a birth partner and post-birth partner. "If you've had a baby and you want to help new mothers, do a short course with Britishdoulas.co.uk and work locally," she says. "You do what a grandmother or sister might do for a new mum, such as giving moral support, helping around the house, caring for the baby and supporting the whole family."
Did you know you can rent your room or house out at Airbnb? They have been around since 2008 and millions of people have been renting out their rooms or entire homes to travelers from all over the world. If you do this right, you may be able to cover your entire mortgage! If you’re going to be gone for a month or two, you may as well allow your space to make money while you’re gone.
Because watch repair is very specific, general repairmen may not be fit for the watch repair business. Those who’re experienced with repairing small mechanical items, however, may find watch repair to be incredibly fun. Those who enjoy collecting watches and clocks, too, may enjoy the art of watch repair. As a business owner, a watch repair shop owner will need to have a good handle on management, accounting, and marketing.
Yes, you can turn your car into a money-maker by driving for Uber and Lyft, but there are other ways to convert mileage into money as a clever side business idea. One way is to do vehicle advertising, a potential side income source of anywhere between $100 to $600 per month. Whether you own a compact sedan or a full-sized bus, your vehicle’s exterior space is prime real estate for ads. Check Wrapify, carvertise, and similar sites for more details about getting started with this business idea and for being paired up with local advertisers.
If you speak like James Earl Jones or Scarlett Johansson, quite a number of digital publishers (including game developers, animated film-makers, and training video producers) pay good money for voice talent and the time investment isn't too intensive—making this a great side business idea. You can find these publishers looking for voice-over artists on sites like PeoplePerHour, Freelancer and Upwork, as well as their calls for talent directly on their websites or through voiceover agents. If you do pursue this as a side business idea, be prepared to invest for the long-haul as it can be a very competitive industry.
This is probably the side hustle I have the most fun doing. I have been buying and selling both VW Campers and mopeds since I was in college. While I sell a lot more mopeds that VW campers, but when I find a good camper deal I don’t hesitate. I love VW Westfalia Campers from the 1970’s and 1980’s and have owned 2 over the past 10 years. They have gone up a ton in value over that time, but you can still find deals on them locally.
It sounds too good to be true—getting paid to represent your favorite brands at events across the nation. But, if you have a friendly and outgoing personality (a growing social media following helps too), you can forge a potentially paid relationship as a brand ambassador with companies who want to reach other people within your community with this  side business idea. As a Brand Ambassador, you do anything from demoing the latest technology, to passing out free swag at music festivals, to going on nationwide tours, to pumping people up as a mascot, and more. Depending upon the gig, you can expect to earn anywhere from $18-$100/hr. You can get started as early as this weekend by joining the Brand Ambassador Facebook group for your nearest major city (e.g. join the "Brand Ambassadors of Seattle" group if you live in/near Seattle). Once you've been approved to the group, you'll get access to daily job postings from big brands and agencies with opportunities in your area. All you need to do is submit your resume and headshot to apply. For a step-by-step guide on how to get hired for the best gigs and the highest pay rates, I recommend checking out The Brand Ambassador Blueprint.
The type of business that requires active owner participation at all hours of the day may not be the best if you’re working a full-time job. For example, if you open a service business and customers want to see you during daytime hours, you’ll be limited to only your lunch break. In addition, it’s typically a bad idea to take phone calls during your full-time job or communicate via email. The best type of side business is one where you can dictate your own hours. After all, you don’t want your side business to endanger your full-time job or vice versa.
Do you play a musical instrument well enough to teach it to others? How about taking your skills at producing music or sound design and teaching others as a service-based business idea based on your experience? Private music instructors in all disciplines charge upwards of $20-100/hr (or more depending upon skill and experience), and you don’t necessarily have to do them in person, either. This makes for a great side business idea that can channel your passion for music into profits.
Treat your business finances like your personal finances. You should be creating and sticking to a budget for both, allowing you to make your money work best for you. It's also important during this time to sock away as much extra money in savings as you can, to prepare for the transition from your full-time corporate job, to working for yourself. This is probably the biggest mistake I made, as I quit work in a huffy with only $3k in savings. 
Maybe you’ve always had a knack for repainting old thrift store furniture. Or maybe you’re a gifted musician who could coach other young aspiring talent. Maybe you have a specific education, training, experience or skill that you could develop into a freelance business such as financial planning or graphic design. Whatever your “thing” may be, there are plenty of good reasons to get going.
If you are always trying out new hairstyles and enjoy working with hair, then this could be the perfect side business idea for you. Start with a specific tutorial, such as a how-to on making stylish braids. You can upload videos to your website or store demonstrating each type of braid, and produce a guide that gives step-by-step instructions for each.

If you have the gift of gab, public speaking is a worthwhile side business idea for you to pursue. Many authors, medical practitioners, scientists, artisans, politicians, and other subject matter experts earn extra income by delivering speeches, seminars, and presentations. Professional motivational speakers earn an average annual salary of around $90,000 with just that portion of their income, making this a very realistic side business idea while you continue practicing your craft.
I surprisingly get a lot of people asking to detail their car. I never intend to make a business of it, but I love doing it to my cars and people ask me to do it to theirs. All it takes is a cheap orbital buffer (mines a used craftsman) and a shop vac. I normally get easily $100 for a basic wash/wax/vac, or $200 to remove scratches and polish then wax the car.
