Book trading website using openlibrary.com & isbn.com api

Please read carefully and all before bidding. thankyou I want to build a site where local users can add their books on a virtual shelf and have 3 options: - Only add the book (if its a textbook more fields required) - Sell (buy now) - Trade (with other members) - When the member adds a book: A dialogue box appears , ISBN is inputed and the book's information is pulled from [login to view URL], isbndb.com. if the member wants to sell the book , he enters the price he's willing to sell for and payment details. - If book not found, Member must: retype ISBN number (just to make sure no mistake)+ add title + description + book cover. - When user finds a book he wants, he can either, buy now, or offer to trade with one of the books on his shelf when book is offered for trade , the seller receives a notification in the inbox that another member wants his book and he is free to choose any book from the buyers shelf. If he is not interested in any book he can push the "not interested request payment" bttn. the buyer than receives a message that tells him to pay for the book. - Each member has a shelf with a unique url for ease of sharing - Messaging system like Facebook - Shipment process area: once a book is confirmed sold or traded it goes to the shipment in process area , where the seller receives all information about shipment and once shipped can check off "book shipped" - buyer + seller rating - add book review - member notification by email - member settings area I have constructed a very detailed prototype on flash, but i need to explain how to use it. I will only show the winner of the bid the prototype. Core features: (aka very important features ) IF YOU CAN'T MAKE THESE PLEASE DONT BID. 1. Ability to pull book data from database api ( [login to view URL] and [login to view URL]) after the data is fetched it should be transfered to my own database so that next time the person searches, the request will stop when the book is found on my database. 2. 3 payment options (Gateway) . paypal , google checkout , and moneybookers. the member should setup each method, and when the buyer buys the book , he can directly go to the appropriate site complete the transaction and come back to my site to a CONFIRMED PURCHASE PAGE. IMPORTANT NOTE my website will not be involved in the transaction, the buyer is directed away 3. Use google maps api to map where book is located and to be able to show books closest to buyer. 4. Login with Facebook , login with google or sign up. The website should be VERY WELL designed. using graphics and shades and clean effects.
