Php Mysql expert needed for projects

Hi, We need someone with great PHP / MySql experience. We have projects which we've found with bugs and need someone to go in and troubleshoot and resolved these bugs. You can quote your hourly fee in PMB and after I show you the URLs, estimate how long it'll take to fix up and adjust your bid fee. In your bid I need you to post 3-5 samples of your projects, just 5, please do not send me huge list of works. I am looking for skills in AJAX also and web 2.0 technologies as there will be extensions to the projects. thanks
