424238 Popup Modal Window & Form

I am looking for a programmer proficient in jquery and PHP to do the following: 1. Create/provide a lightweight script in jquery that will create custom sized, centered modal popup windows with a darkened background upon clicking a link, and closable via a graphic "X" button in the top right corner. 2. Create a jquery based, PHP powered/AJAX form which allows a user to select their mobile phone from our database of phones (first via brand, then model) and save their selection as a cookie. Please go to [login to view URL] and click the "no phone selected" link on the top right for an example of what I want, albeit I do not want an exact clone. You will need to create basic PHP server side code and test case brand and model array data to test your form. I will complete the code with database connections, queries etc. Please comply with XHTML 1.0 Transitional standards for all HTML. All source files must be provided upon completion. Most importantly, all coding must be semantic and to the highest standard. Speed and optimization are also paramount. I will not accept poorly coded work. Thank you!
