ISBN search bar new and used books magento

I have an online book store, we sell and buy books from the public. the best way to explain what we need is for you to go to this website [login to view URL] and enter and an ISBN number or numbers in the search bar, feel free to use this two 0547618395, 0547647085. If you've taken the time to actually check out the site and, search the ISBN number and press search, that's exactly what we need all of it can be achieved with the Amazon API. We actually already have a working version on our current site but we are building a new magento store. Ideally we would like to explore the option of incorporating what we have to new magento store. All the code that delivers the information we want the customer to see after they enter an ISBN number is already written. Cutting a long story short if you have experience setting up Amazon's AWS API, Amazon Associate program and any of the above sounds familiar please feel free to contact me on (Removed by Freelancer.com admin) and lets spend a few minutes on the phone to make sure that we are all in the same page. NOTE: This is a time sensitive project so please only respond if you are willing to start working on it right away. In regards to the magento store its already built.
