iPhone / iPad simple application

Looking for a simple iOS application with four tabs as follows: 1- News 2- Photos 3- Purchase 4- Status "News" will provide latest news through a XML feed. "Photos" will provide latest photos pull from server and will be categorized in folders. "Purchase" will have two categories, both supporting InApp purchase model. It will also integrate Facebook and Twitter integration to publish on them. "Status" will show stats of purchased items, along with user country, and a few more items (to be discussed). There will be an "About" button that will tell user more about the application. Admin: As admin, I would like to be able to update the News and Photos section without issuing a new update to the app. I should be able to add new items in the Purchase option easily, either by making a new built, or through the web. This is a time sensitive urgent app project. Please do not bid if you don't have the background, time, or resources to complete this in shortest possible time.
