Website design for Book purchasing site

I am looking for someone to design a website that will enable my site to purchase books from visitors. This site will have to utilize the data from Amazon.com. Amazon provides Amazon Web Services (AWS) for programmers. This site will allow customers to enter in the ISBN of a book. The site will then be able to make an offer for the book based upon certain AWS results for that title. This criteria will be based upon AWS results for price, rank, and year published. The site will allow customers to enter multiple books at one time. The customers should should then be able to select the books they want and add them to their cart. I would then like to be able to print a shipping label for the customer. Here are some other sites that provide a similar service: [login to view URL] [login to view URL] I am not sure what this would cost so I selected the lowest option. I am open to higher amounts.
