Interface design for building strategy online game

Hi all, Currently I am developing an online game in the "build strategy" genre (such games like "Anno 1602" and "Sim City"). Right now I need the interface design. It can be quite simple, but should be very functional, and be designed for touch screen. During the game a bar should appear on the upper half of the screen with the current resources available. The height and width of the game screen is dynamic, the minimum size of the game is 800x600. So I would prefer a bar with length of 800 pixels. In addition, I need a menu that can be 800x600 pixels great. This must represent the options (screen size, performance, etc), the build menu with different categories (houses, industrial, embellishments, etc) and a statistical overview. It would be nice if the potential freelancers have already experience in interface design. Due to the small budget I am also open to hire talented inexperienced people. However, a reference with sample images would be nice. In that spirit, I hope for the right people and a good working relationship.
