iphone radio app fro weffen

Weffen, please see this page of comps I did for the Buzzplay APP [login to view URL] I will provide all graphics, images, design assets, I just need to know file types and dimensions needed for the app. I need all the functions you see here to work. Search by keyoword, list stations alphabeticaly by name list newest, oldest, most popular etc. I need all the information to display corectley for each song ( image, title, etc. We need the ability for thus user to add a favorits list. We need a volume slider. We need a next track butoon adn previous track button. I have a server and a php mysql data base that can be used to develop this. Please let me know the best way to move forward and how long it will take to complete this phase. Thank You LJ
