Comparison site script

I want a PHP script like the one behind [login to view URL] and [login to view URL] If possible, I don't want the script to only be able to be used for a book site. I would like the script to have the ability to work with any type of product. For instance, if you wanted a comparison site for dvds, computers, athletic shoes, etc. I want to have the ability to include an affiliate ID in the search results and I don't want to get into affiliate datafeeds and what not, so please avoid that. I am only interested in the search portion of the script that is used at [login to view URL] and [login to view URL] I don't want vendor ratings, the become a member option, or the directory structure that is included at [login to view URL] ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. 3) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 4) All deliverables will be considered "work made for hire" under U.S. Copyright law.
