Additional Features for a realestate site

My client wants to mimic two features of: [login to view URL] He wants to have the "New Property Notifier" and "Shopping Cart" features of this site adapted to his site: [login to view URL] I dont think this will be teribly difficult but I just don't have time to do it myself. This is not a real shopping cart as you will see, its just a place where users can store information about properties. I can work with the bidder on fitting these features into the look of the site.
