I am not a team, but rather a full-time freelance developer. Located in EST time on the east coast (New York City). I have experience with all of the things you mentioned: PHP, MySQL, HTML/CSS, Joomla, Wordpress, and more of course. I'm ready to start today on getting the Joomla site up and running from your PSD files (will ensure cross-browser compatibility, use latest coding practices: table-less layout, W3C valid markup, optimized according to Google Page Speed recommendations, and so on).
