474286 Mobile Application Interface Design Iphone

We are looking for a reputable design company to design the interface for a mobile application. The application would have only 3 or 4 unique screens. However the home screen and would require two versions, one horizontal one vertical. We would need the mash up be done in Photoshop, and then pieces (like borders, background) be separately sent to us. At last we'll need the copyright be signed over when the project is finished. We'll of course expect confidentiality after the project is done. Details will be sent to the winner.
