Need simple ipad app

I have a website that allows people to write free ebooks. I'd like a simple ipad app made that lets users read these books on the ipad offline. The content of the books is all html, and I have an API set up to allow the app to connect to my website. example image: [login to view URL] functionality: - must work on all ipad models (bonus if you can get iphone to work also) but the app has to be primarily designed in native Obj C for ipad. - basic functions include browse and search for books, add to library, books in library can be downloaded for offline use - basic settings to change font size while reading, bookmark, and other basic reading options set via the api - ideally id like some of the reading options seen in kindle app and ibooks, like the ability to change brightness, paper style etc. - user log in / registration Please message for more images of the app.
