דרושים פרילנסרים לUI design for a social app

Hi!
I'm looking for a UI designer for a social app, build more as a game.
The project includes:

* 1 main page (its a one screen a app)
* splash screen (for when the app is being loaded)
* connect to facebook screen
* home page button
* 1 preferences menu

The app is already characterized.
However, there are no wireframes

If interested, i would love to see previous work, especially from the fields of gaming, practical utilities and social.
Also, please explain (in general) how many hours you think it should take you, and how soon can you start working on the project.

Thanks, Amir.
