AJAX PHP Order Display

This is a login and one page project. We have an existing MySQL database with the relevent queries to feed the display already written and populated. This is set up on a development server we can give you FTP access to for development period. We need a simple login form that will check email address and password against those already in the database and then hold a PHP Session with the users ID. Once logged in they will go to a single page as illustrated in the attached screenshot. In this page: "Item 1" displays the company name from the database "Item 2" is a scrollable div of all the orders in the database for that company. Each row must change colour when the mouse hovers over it. On clicking a row then the content of "Item 3" must be updated with the relevent order details using AJAX. "Item 3" contains the order detail information. Initially this is blank but when a row is clicked in "Item 2" then AJAX populates / re-populates this. This is for display of order information only, no updating of data is required as that is already handled by a back office application. An thats all that needs doing. It needs writing in XHTML Strict, tableless (divs) with all style in CSS; must be W3C validated. For the AJAX you may use [login to view URL] It must be written and checked to work in IE6, IE7, Firefox 2, Firefox 3 and Safari
