Build at least one project that looks nice. You don't need to spend a lot of time, but buy a nice-looking theme (I used themeforest) and build a simple site for a small business. Then hit up your non-technical network. Show them that you can give them an attractive website, and you'll probably find a few people who are interested in working with you.

When I first started freelancing, I spent 10 hours on a redesign for a local fitness boutique. It was an easy project that earned $700, but I would've done it for free if I knew all the business they'd send my way after. After seeing the site, the receptionist's brother wanted a website for his bike store, another client wanted a new site for his business, even the guy who cut my hair wanted me to make him a website after seeing the one project I had done.

If you can't find anyone in your network that's looking for help, try contacting local businesses with crappy websites. You can create some screen-shots of a potential redesign or even create a working demo page using pre-built themes (check out trial.mysitemyway.com). You'd be surprised at how many projects you can get from this type of outreach.
