Work remotely for a call center. Because many call center jobs are location independent, finding work in this field is an easy way to earn some money from home. Dozens of sites list job openings for call-center representatives, including Freelancer.com and SimplyHired.com. Meanwhile, you should check local job listings for openings and opportunities as well.
If you are good at writing notes and attended all lectures, you can sell your asserts to less committed students via NoteSale. You can create a listing for free, but the site will take a per cent from each of your sales. Typed notes in PDF/Text format sell best, yet it’s worth trying with scanned handwritten notes too if you have nice clear writing.
Websites like Care.com connect parents with babysitters. The company does all the background checking and other due diligence to put parents' minds at ease. Of course, you can appeal directly to people in your personal network, but if you're looking to generate recurring revenue sign up with a site marketing to parents looking for child care services.
