amazon appstore

I need a content-based Amazon appstore-ready application template and an introduction of what is what so I could add in-app content into it in the future and publish the changes into the appstore. The main aim of the app is selling copyrighted materials through the app menu with 1-click. There will be of course a few free articles in the app. The app template should support all the kindle fire devices including latest android versions. It has to have a simple design and the backend that can add articles to have them appear in the menu-buy section. Once we agree on the price you provide we may in the future buy support and/or updates of the app template from you.
