Iphone App: product catalogue

Our client wants to have an iphone (and possibly android) app made that displays their product range in a good way. Simple rundown: When you start the app it should display a logo + able to chose between main product groups (2-3 groups) When you select a group a product in that group appears and you should be able to scroll left/right to navigate the different products. There is not that many products in each group, maybe 5-10. (We are talking simply displaying pictures here) Small button on each product which you can press to open a page with product information (The information is text based, we ill provide finished formatted text, if its more convenient having it as images we can do that also). Button with link to the company website that opens the URL for that product in the browser in the iphone. We will provide top quality high res images of all products and logos needed according to your specifications.
