There's a couple sites dedicated to finding PHP jobs too ("php jobs" in google will return a tonne), I signed up for guru.com which has a section for it as well that seems to post some nice high paying jobs, but I didn't like the whole process over there too much so I've just been ignoring it lately.

Have you tried craigslist.org as well? I found it was a pretty good place to hook up with some freelance work and there's a lot of companies that post good jobs on there too.
