Reskin/Redesign iphone application

Ok, I have an iPhone APP that needs reskin and new interface design. The main function is the design, but the design needs to be setup in the application as well. So I'll send you a zip file with xcode5 files containing these files: (see APP [login to view URL]). So you make the work and send it back to me. The design has to be approved by me. I want a bidder that CAN think by himself and is SMART and has great skills and experience. So not time wasters here. The main requirement is for the bidder to make the app REALLY GOOD LOOKING. The aesthetics of the app and usability is the main thing here. The text, logos, buttons need to be readable and pleasure to use. There will be some adjustments on the text too: I'll send the rewritten text for you. !!! READ THE ATTACHMENT BEFORE BIDDING. !!! LET ME SEE YOUR PREVIOUS DESIGN WORK. LINKS TO PORTFOLIOS PLEASE. MUST HAVE APP DESIGN BACKGROUND. Happy bidding!!!!! Best Regards, Aake
