There's a huge growing market for mobile phone accessories, and plenty of handmade sellers are raking in 6 and sometimes 7 figures from their phone case businesses. You can get your own phone case business up and running as a side business idea in a matter of days with turnkey solutions from Case Escape, my previous company, and you can now get ready-to-go kits that'll give you everything you need to start a phone case business. Once you're up and running, you can sell cases on Etsy, Amazon Handmade, and Fancy. During our first year of selling phone cases as a side business idea on our Etsy store, we made around $60,000 in revenue from that selling channel alone—not to mention additional sales from fairs, trade shows, promotional products vendors, parties, events and other online marketplaces. From there, the sales only continued growing and we graduated from side business idea to full-time company that I ran with my best friend for multiple years.
If you’re particularly adept at a subject and you find teaching to be a rewarding experience, a home tutoring business is a great way to supplement your income without taking up too much time. Tutors often charge between $30 and $40 an hour and with 3 students a day for 5 days a week, you can supplement your gross income in the amount of $450-$600.
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.
