New Car Price Quote Script

Hi, I need a price quote/lead generation system for "NEW CARS", similar to edmunds(dot)com, autobytel(dot)com, kbb(dot)com, etc. Because I am not sure of the specifics behind those scripts I hesitate to use the word "clone", but... I do need a script that works almost exactly like those sites' new car price quote systems. If you have worked on a lead generation or price quote site or have an understanding of how the front-end, back-end and the admin is setup I would appreciate your ideas and suggestions as well as your bid. The basic idea, as I see it, is.... First, the "dealer sign up process" should allow car dealers to sign up and add to the database, their contact info, the new car makes and models that they sell, etc. The dealers would need a login member area to check leads, change contact info, make account deposits, etc. Then when a new car shopper/website visitor requests a price quote, the script would match up the closest nearby dealers based on zip code. It should contact and inform those dealers that they have a lead in their area. Also, I would obviously need an admin to be able to easily add basic info about new car models. For example: msrp, availed trim packages, other make and model information. As well as other basic admin functions, like managing dealer info, stats, deposits, etc. You get the idea. If I've left anything out or you have any questions, just ask. Thanks.
