Design Screens for Mobile App, Similar to DrawSomething

Seeking an individual or resource with strong user interface and mobile app design skills. I have 2 mobile app games that I need screenshots designed, without any programming. The apps are "head-to-head" concept, similar to DrawSomething, and will have the same number of screens to DrawSomething. This project will entail designing all the screens for each mobile app, along with text and screens that get pushed to Facebook and a corresponding website for players to keep track of their game records and also have an auction section, similar to Ebay. Each game will need a fresh logo and design. Each game will need to seemlessly integrate into the website. The selected vendor will need to sign a non disclosure agreement and transfer all copyright/intellectual property. Once again, I just need solid designs for each page of the mobile apps and website that can be easily transferred to my programmers. There will be no programming required by the winner of this project.
