Online Auto Auction -- 2

I want to create a web page to buy cars online from the auction (Copart, IAA, etc.) using my dealer license they can search it through car specifications, # of the lot, vin number. I want to implement the live auction as well from different auctions and offer the transportation from a third party, I want to have a section where they can look for parts from AutoZone, Amazon, lkq, aftermarket and be able to charge a membership to buy the car, a fee for the transaction of buying parts and cars and also for the delivery of the car and the parts
