In the Bay Area and NYC, a self-taught coder can find work without a college degree. I recommend that you work very hard on your Rails skills, build a website all by yourself using rails, and put the source on github. If your site works, looks good, and you know how to present yourself in an interview, you can get a paid internship at a startup that uses rails. Of course this doesn't solve your short-term cash crunch, but depending on how disciplined you are, you might not need to finish college right now.
