One of the surest ways you can make cash if you're in a bind is to sell items on Ebay or Craigslist. Any used items like furniture, household appliances, collectibles or anything else that you're just not using or is collecting dust, can be sold online to make some money. If you're serious about this, you can even do it professionally for others and collect a small commission for each sale. Take quality photos and write a good description and you'll be in great shape.
This business is ideal for current and former teachers, which is why many teachers begin their home tutoring business as a part-time job. You must be a people person, as most of the business regards direct, one-on-one interaction with others. It helps to be good with children of all ages, as they comprise the vast majority of your customers. Finally, it helps to be organized and self-motivated: conducting home tutoring as a full-scale business means managing many contacts, reaching out to local schools, and making sure you have enough time during each session for your various clients.
With the rise of online craft marketplaces like Etsy, people with decent artisanal skills like sewing and woodworking have an always-open market to sell their products as a side business idea. If you’ve always wanted to design and make clothes by hand, then you can start turning those fashion ideas into real, hand-sewn garments and earn a little bit with this side business idea while you sleep and customers from around the world browse your Etsy & Amazon stores.
Even if you have an income stream that makes up to 90% of the money. When working for yourself, you'll need something different for that other 10%. This not only provides an outlet for creativity but diversifies your income in the event something happens with that primary revenue source. Again, this may not work for everyone but for ME and MY EXPERIENCE, being able to branch out into other ways of making money besides freelance writing made my time as a solopreneur a lot more bearable.
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.
