If you have a passion for fitness, you could consider becoming a personal trainer. A lot of people simply need accountability and a little instruction to get going to get fit, and a personal trainer can help with this. And that's just the beginning. If you get a following, you could turn your passion for fitness into something big like Steve Kamb did with Nerd Fitness.
Cold calling still exists, and businesses are always looking for people willing to man the phones and make calls. Many companies hire this in-house, but there are also firms that hire telemarking professionals to man phones as well (especially around election time). If you don't mind being on the phone for several hours and getting hung up on often, this is a good job for college students.
Lander > Offer: This is a much better approach than the above. A lander or landing page is a web page that you create and that acts as a middleman between the offer and the visitor. This could be a review of the offer, a video, an article…etc. The visitor would land on it, consume it and then click a link and get redirected to the offer. Warren Wheeler’s case study on AMNinajs.com uses a variation of this funnel.
Coding and programming. Yikes. I took a programming class one for a semester in college and it was the toughest class I’ve every taking. Trying to learn code is like learning a foreign language. LOL. I really did enjoy your site though. Such a helpful site for helping people make money online. I know a few developers who would love the information on this page. I’ll be sure to let them know about it. Great Stuff!
As for other tips, all I can say is “a penny saved is a penny earned”. If you are running out of ideas to make money, start saving. Some quick “low hanging fruit” tips to save some quick cash include – switch to MetroPCS or Boost for cellphone (I only pay $20/month), switch auto insurance to Insurance Panda ($25/month), and start using GasBuddy (saves me like $100/month at least. I drive a lot).
If you have anything you don't use anymore, and it's too large to sell online, Craigslist should be your go-to place to sell stuff. In college, you may want to sell all your furniture before moving home from school at the end of the year. Depending on what you own, a few $100 might be better than storing it or transporting it back with you. It's easy to setup a listing and sell anything on Craigslist.
Have you ever seen those roadside stands around Valentine's Day and Mother's Day? You know, the ones selling flowers and treats? Well, that could be you. As a college student, just head down to Costco and buy some flowers and holiday candy. Then, get permission to setup a stand near a busy intersection or on the side of a road. You'll double or triple your initial investment every holiday.
