Graphic Design of the User Interface of an iOS App

We have an universal iPhone/iPad app in iTunes App Store([login to view URL]), and we want to make it look nice and easy to use. You will work on the graphic design of our user interface (such as icons, buttons, menus) including : 2 Launch Image (1 for iPhone, 1 for iPad) 2 Main User Interface (1 for iPhone, 1 for iPad) 2 Settings User Interface (1 for iPhone, 1 for iPad) We hope you use colors and styles just like mobile safari, and don't change the users' habit to surfer the web. You need to be a Photoshop master and be familiar with the graphic Design of iPhone/iPad User Interface. You'd better have a iPhone/iPod/iPad and try to use this app to grasp more potential requirements. Please send me some samples of your previous similar project via PM.
