ajax module for displaying properties

hello, I need to develop an ajax module to have my properties scrolling on my site. In order to have always new properties on the main page. I want all properties to be scrolling on the main page. Like this a user can see all properties without moving the mouse, and if you enter the site at 2 different time, you will see different properties. Properties will not be displayed on 2,3,4th pages as they are now...there will be always a movement. I also want properties stopping to scroll when user put the mouse over it. and properties will be clikable in order to have more infos. each time the admin will add a property to the database, the property will be part of the module and will scroll with the others. [login to view URL] is the site where I need this module to be implemented. The module will be implemented also on 15 clones. thanks
