Ask HN: how to find contract software development?

First time poster over here. What's up. My question to Hacker News is how one goes about finding contract software development work. I would be interested in doing just about anything from small websites to big mobile apps (as long as the price is right, heh). I just don't know where to look for this kind of work, especially since I'm just starting out of college and realistically don't have much to show portfolio-wise aside from odd course work. The main goal I have is to finally start making software for actual paying customers who care. I know I can deliver some good work once I get my foot in the door. So, where does one find all these customers for contract work?
