Shopify Store iOS App

Create an iPhone & iPad app for my Shopify store. Very simple, just use the shopify APIs to connect to the account or just a simple HTML link would work too. My shopify account is at iTattoo.com. I want the app to show all the categories of products and then a thumbnail listing of All the products in that category with paging. Then the user should be able to pull up the individual product descriptions after clicking on an individual product thumbnail. If the user wants to buy I want to do it thru the app and not in app purchase. Just need you to develope it, I will upload it and test. I want it developed in Xcode, no exceptions. I want beta and test versions delivered as an Xcode project, no exceptions.
