GoodProducts Application (fb)

Looking for a very good .NET developer person or team. This/these individual(s) has/have to be strong with JavaScript and AJAX. Looking to develop a site that is fully AJAX driven for a non profit organization. 1) The site will link users somewhat like facebook. 2) Users status updates will appear for people they are connected to. 3) Minimal refresh of the browser is a must have (AJAX). 4) Want people to be able to write applications and have them added to the site like facebook. 5) All applications launch in a specific container (<div> tags) on website. Applications that are not in focus are hidden or display:none to the user but an icon at the bottom of the page (No Scrolling) will display the opened applications. The complete site layout has been created and waiting to send to the winning bidder. Thank you.
