Big companies are generally (or at least should be) flexible if you want to work from home a few days a week. But if you want to do it full-time, smaller companies can be a better bet, because your working remotely can help them save on office space. You can probably find lots of startups or small businesses looking for tech help who have the resources to pay your salary, but not to relocate you or pay for additional office space.
Companies need people with all different levels of technical ability to test out their websites, apps and social media offerings. Sign up with one of these website usability testing companies and take on quick jobs surfing the web and playing with new apps. It’s not a career, but it is an easy way to make extra money from home. The only thing to keep in mind is that this won't likely be a steady gig, just occasional. Learn more about website testing.
What’s the catch? None, really. Cash back apps act as affiliates for many online merchants, which means that whenever you make a purchase through one of the apps, they get a small commission — but then, they give you a portion of that commission as “cash back”. For example, if I buy a pair of Nike shoes through the Ebates app (or website) and spend $75, Ebates may get a $10 commission but then they’ll pass $7 back to me. It’s basically a way to get sale prices on stuff that isn’t on sale!
