Any suggestions on good places to find freelance developers?

I was wondering if anyone had any tips on places to look for freelance developers. See, I run a small web company (just me and my developer partner), and sometimes we get a lot of job offers in the pipeline and we like to have some freelancers in our rolodex in case we need to contract out work. Finding designers is fairly easy since I'm a designer and I'm in the community, but I'm not plugged into the dev community. I would like to know some good resources should a time come when I need to reach out. Any tips? p.s. When I say developer, I mean someone with PHP and MySQL server-side experience and XHTML, CSS, and Javascript client-side experience. Thanks.

What's your problem with freelance developers?

Well, I don't know about PHP, but if you're interested in Python developers I can provide you with some references.
