As a novice freelance writer, you’ll need to get some experience under your belt before you can start grabbing for lucrative writing gigs. Although many people slag off content mills such as TextBroker (which turn out bulk content and don’t pay very much), students shouldn’t ignore them as they are a place to earn guaranteed money (even if it’s rather low money).
These little jobs are done by people who log on to a company’s site and choose tasks, which could be as simple as clicking a link. Amazon's Mechanical Turk is one of the most well-known sites of this type. Also, there are crowdsourcing projects, which are similar to data entry, where companies engage an army of virtual workers to each do one small part of a larger project.
