CSS, Photoshop, Ajax & PHP - App GUI Redesign / Update

I am looking for a graphic designer/ coder to redesign the user interface of my web app. You must be know and understand CSS, Ajax, jQuery and PHP and above all have an excellent design sense for designing easy to use (simple) GUI's. I will work with you on mockups and then once approved will need you to implement the changes/ updates in as few lines of code as possible... You will also need to remove and unused code from the current layout. The new layout should work for all major browsers (Firefox, IE, Chrome, Safari) as well as for iPads and mobil phones. Some of the options of the app require Ajax or jQuery functions. Here are the screens components that I need redesigned... - login screen - remove sidebar - redesign send message screen - redesign how data tables appear (also add toggle expand function to records) - redesign standard buttons and add standard icon images - tips/ help comments Please submit at least one GUI example that you have designed and implemented.
