AJAX / Javascript programmer needed - ongoing

I have one project we're trying to finish up right now that needs some AJAX written to interact with a PHP backend. More generally, I'd like to develop a relationship with someone who is extremely strong with JS/AJAX. I'll have a lot of small projects moving forward. I am a former C programmer who can handle any MySQL / PHP issues, but front-end is not my strength. Accordingly, the nice thing about working with me is that I think like a programmer, so the project scope and requirements will be very clear and realistic. Most of the projects will be fairly limited 1-2 day engagements. Timetables will usually be flexible, so you can work on them for a few hours at night, etc. **Here's the key: I am looking for a very solid programmer. If you're not lights-out (extremely proficient) with AJAX and Javascript, don't waste my time or yours. Expect to provide prior code samples. Thanks for your consideration.
