Develop Code for eBay Sniping Web Site

I need a program that will allow eBay bidders to set a maximum bid for an auction at my site and the program will place the bid for the bidder a few seconds before the auction ends (number of seconds is configurable). The interface will be a simple Google-like search box where the bidder will enter the item number of the item they want to bid on. This will generate a pop-up that will show the Name of the item, the item number, possibly a thumbnail of the item, a box for them to enter their maximum bid, and a drop-down menu for selecting the number of seconds before the end of the auction that their bid will be placed. I will also need a screen showing a summary of each bidder's snipes. For an example of the kind of design I want go to [login to view URL] ## Deliverables I forgot to mention that the bids generated by the program will need to contain my eBay Partner Network affiliate ID.
