ISBN Barcode reader

Hi, i would like to make an app that allows the user to use their camera to scan an isbn barcode (or type in the isbn manually) to get a price and info on products from large stores such like wal-mart, target, best buy, and others. The app will need to connect to the internet to search the products. App should work on all devices with OS 4.5+ and should be developed first for the storm2 touchscreen device. Please bid with an accurate bid and with any samples of work. Do this part of the project well and there will be expansions on it! I will own all rights and source code to the application.
