Modify auction theme into reverse auction theme

I need reverse car auction site. If it is easier for you, you can use some Wordpress (or some other) auction theme (there are many) and just modify it into reverse auction theme. I can buy the theme separately if needed. The design and feeling of the site should be inspired (not the same but inspired) by this site: [login to view URL] Here's detailed discription of how reverse auction site should work: Homepage Buyers. This page needs to have a link to where buyers can create account to start a bidding war, or sign in to their current account and see bidding wars in progress. To Create an account we will collect name, address, d/o/b, email, and phone number. Car Dealers The home page will have another button for dealer's to create an account, or log in to an existing account to see current bids in progress. To create an account for dealers we will collect the dealership name, address, contact person, phone, and email. A dealers account however will not be setup immediately like a buyers. After they submit their information we will reach out to them directly by phone to verify the information then we will set up the account on our end. Bidding: Buyers After buyers create an account, and begin a bidding war they will be asked how they plan to purchase. (cash,finance, lease.) For now under the lease button it will just say coming soon, I won't know how to effectively implement that feature until later on so don't worry about it for now. The only difference between cash, and finance is that finance offers will include payment estimates. Also for finance the buyer will have the option to upload their credit score. That will be done using optical character recognition, and I'm having a separate company build that feature. When a buyers sees the offers (for cash, finance, and lease.) the only information about the dealer they will be able to see is the dealers rating, and a vague distance range ie: less than 50 miles away or more than 50 miles away etc. Also there will be a messaging system so the dealers can ask the buyers questions. However the only way the buyers can answer is by selecting "yes" or "no". Dealers After the dealers accounts are created that will be able to search for active bidding wars of their Dealership brand. Meaning Toyota dealers can only see Toyota auctions, Ford can only see Ford etc. They will be able to search by distance, and by model. Similar to what the buyers can see, besides what the buyers wants (Make, Model, Options etc.). Dealers will only be able to see a buyers a rating, as well as the same distance range, and the buyers credit rating if applicable. They won't see the exact score like we see, however what they see will only say Very Good, Good, Fair, Poor, or Very Poor. In addition the dealers will also be able to see what other dealers are offering, as well as that dealers rating but nothing else. As stated before the dealers will be able to ask buyers questions, but there will be a note next to the messaging box that buyers are only able to respond with yes or no so they must word questions accordingly. (Did a member of your current household graduate college in the last 4 years?..etc) Buyers will be able to decide if they want the Bidding war to last for Three days or Five, however a buyer can accept an offer at anytime before that if they choose. Once the buyer accepts an offer all of the losing dealers will be notified that bidding has stopped, and another offer has been accepted. The dealer that won the war/auction will be notified, then given the opportunity to purchase the buyers contact information so that they may consummate the deal. If for whatever reason the dealer does not purchase the contact information within 72 hours the buyer will be asked if they want to re open bidding or accept another offer.
