I think for a college student, the most ideal way to make money is by learning graphic design or video editing. I'd recommend getting good at either of the two (Photoshop or Premiere Pro), then market yourself on Fiverr (like jiggin said). I've found that a lot of people don't really want to do the design work themselves, so I can make some easy cash by doing it for them!
Or, if you are really ambitious, you can look into affiliate marketing. I've gotten pretty good at this one, and I can safely say that the payout is really nice! Essentially, companies pay you to market for them. Feel free to message me if you are interested in this option, I would be more than happy to help you get started! =)
