iPhone App UI & Graphic Design

I am currently developing an iPhone App and I require a some graphic design work to be completed. The app is an information-type app that displays data and images from a web-server backend. I will be doing all of the programming, I only need help with designing the user interface and also some custom graphics. The graphic design I need includes: -General User Interface layout design and data visualisation -User Interface elements such as buttons, menu bar, navigation bars etc. -A single character design that will interact with the user -The character will need to have some animations -Icon Design -Miscellaneous Marketing material for the app (such as graphics for the website, promotional posters etc.) The character mentioned above will be a cute little robot. The pictures below should provide some inspiration: - [login to view URL] - [login to view URL] There is a significant amount of work available here for the right person/team. We will start out with the UI layout and the character design, and if we are happy with that work we will progress with the rest of the design work. Past experience designing UIs for iPhone apps is a must and this must be proved with examples of previous work. More details of what the app does and the data that will be displayed will be given to the successful candidate.
