AppStore Backend Management Digital Photo Selling (J2EE))

I want a very simple and basic web application which I can manage my digital photo bundles in order to sell it via in-app purchase in my mobile application(I already have). In this web application, I would like to create image bundles with 1 or more photos. Application should be available to connect with Apple Appstore and my application over web services. The admin should be available to upload images to Amazon S3 server. Pricing will be handled in App Store according to Apple rules. No need to have a good web design. We can handle it later.
