It’s not exactly a way to make consistent great money, but housesitting—exactly what it sounds like—is a fantastically easy business idea that can fund your ability to live in exciting locales around the world (or your city) without paying a dime in rent. Did I mention it’s a way to travel and live rent free? Here’s a list of four great websites from the legendary Nomadic Matt, to start your housesitting side business idea search.
A jam business makes different flavors of jams and jellies, which are packaged into jars for distribution. Businesses may sell their jams to customers directly, or they might sell to retailers. These spreads are put on toast, used in cookies and cakes, and incorporated into many other foods. Jam businesses make different flavors of jams and jellies, which are sold to customers either directly or through retailers.
No matter where you're from or what you do for a living, thanks to the conveniences afforded to us by the internet, making money is no longer a constant and never-ending struggle. With the proverbial world at our fingertips, as long as you know how to tap into the vast amount of opportunities found in the digital ether of cyberspace, you can earn some extra income, even if you're in a tight bind. 
If you’re one of those people who can’t help but flip through bridal magazines and think about various wedding arrangements in your daydreams, wedding planning might be the perfect thing for you. A great way to get started is to develop a website or blog on the topic, get to know people online, and promote your services at local wedding venues and throughout the community.

Additionally, business owners who start this type of business are in good company. Not only do many people have successful children’s book businesses today, but one of the most successful children’s authors in modern history began by self-publishing her work. Beatrix Potter funded the first runs of both Peter Rabbit and The Tailor of Gloucester. The two stories are popular even to this day.
Those who have experience in HR and a thorough understanding of Applicant Tracking Systems  (ATS) will do well. You will need a certain amount of people skills to attract clients, but the results will matter far more than how friendly and personable you are. If 90% of your clients find a job in their field after paying you a visit, these numbers will speak for themselves.

Pet photography, like many other types of photography, can be done on one’s own schedule. You will have to be flexible in order to work with clients and find times that work for both parties, but you can pretty much set your own availability in a pet photography business. Best of all, there aren’t many ongoing expenses, so you could run a pet photography business from your home without very much upfront investment.
From personal experience as a freelance content marketer, I can vouch for the profitability in this industry. I grew my side hustle into a $160,000/yr business before quitting my day job to pursue this business idea full-time; all you need is the right skills and experience to back it up. With startups, established brands, and even notable influencers needing to build credibility and grow their brands, professionals who can serve up compelling content enjoy a huge demand for their services. And, since brands will always need high quality content to bring in new customers, your skills will always remain an asset to invest in—especially since the nature of creating a content marketing strategy is an ever-evolving one. Start by tapping into your existing network with this business idea and begin tracking down local small business owners who could benefit from your marketing tactics, do a bang up job, ask for referrals and grow from there to the point where you're doing blogger outreach and spreading out to a wider market.
AirBnB offers a great resource for people that are willing to rent out a spare room or even their entire home. If you're in a bind for some fast cash, AirBnB offers you an avenue for creating an income. You'll get paid 24 hours after a guest checks in, which is to avoid any problems or potential scams that might arrive. Some people earn their primary income just by renting out rooms or homes on AirBnB.

Whether in the classroom, at the grocery store, or on a job site, there’s always the potential that someone could need immediate, life saving medical assistance. Many SCA victims require defibrillation within 4 minutes of an attack, yet it takes emergency medical personnel 8-12 minutes to arrive after an emergency call is placed. Your assistance in training individuals and workplace teams will, undoubtedly, save someone’s life.

Teaching a language generally requires a person to be fluent in that language. However, a language lover who is still learning might consider teaming up with others who are fluent in order to start this business. Definitely, one must possess a real passion for world culture, and an interest in sharing that appreciation with his or her students. This is what makes the challenges of language-learning worthwhile.

Now that you’ve thought through the myriad of reasons to start a business on the side, the next step is to know what to expect. Some people think a side business will be easy and won’t take much effort. After all, it’s a side business right? Unfortunately, that’s simply not the case. A side business has many of the same challenges and issues a full-time business has. Here are a few considerations to keep in mind.
Choosing the path of entrepreneurship, and working on your side business idea, is without a doubt riskier than being content with holding a 9-5 job. It requires way more sacrifice. However, once you’re reaping the lifestyle benefits of being your own boss and hustling your way into making significantly more money with your business idea than you ever could at your day job, the hard work will have all been worth it. So, let’s talk business ideas.
Firewood!!! I live in a semi-rural area about 1/2 hour North of Newcastle, Australia (houses on normal blocks, 1/2 acres blocks, “lifestyle” type blocks). A few people here will deliver a trailer load of cut up firewood for various amounts of money locally and into the more residential areas in the city. If you have the room to store firewood to season and a log splitter, its a good side income (for winter). I also know a lady who was struggling to find work after moving here. She started doing before and after school care and earns more doing that, than she did working full time in an office previously.
