Game Design

I am looking for a game designer to work with me to develop a game design. I need someone who has previous experience is designing games. The game is ipad portrait style game. The game will be for the ipad and iphone platform. I will need a back ground and some letter bocks of the alphabet. This is a very simple task for someone experienced and should not take more than a day. Also a few menu buttons. The game is similar to Super Stack Attack. Attached are some images of the reference game, my spin and the blocks. I actually put the design togther myself however there are a few details that I want to make nicer. Please provide examples of work. I like to work fast so, though the time to advertise is longer, I usually award as soon as i find my guy! Regards,
