Ask HN: Generating sales leads for hacking jobs

I have just taking steps to start my own company to sell the web development services of myself and my 12 friends, who are now my employees. I have a few long-time clients, but I am looking to get some new jobs coming in so I don't lose my hat.

Any tips for an individual used to just word of mouth that needs to feed 12 mouths now. FYI, I am thinking of hiring 4 dedicated sales people as well, if needed. Any input is appreciated!
