406653 ASPX - AJAX - DB - LARGE FORM

Ok I have all the a huge database with many fields. I need a form to retrieve the data using ajax preferably, then display that data with pictures from the relative file. On hover of the items retrieved, a quick view of the items description pops us. I seen this technique used today on many sites. The pop up is not a windows but like a small square/shape. On click the user goes into detailed view of the items. If user like this item he simply fills out a form for someone to contact him. All his info is trapped in the db with datetime stamp. Review my data and we will need a form to retrieve this data. We will need a form like this [login to view URL] and a more generic search such as hyperlink quick clicks like : 3bedroom2bathinHoustonUnder200k ... CondosIn77007ZipCodeUnder250k etc.....
