Mainscreen Program Graphic Required

I am currently in the process of having a program designed and I need someone to design the opening static screen for the program. The program is realated to horse racing so I guess you will have the run of pretty much designing what you want as long as it still can be shown to relate to horse racing. I need the background designed and then I will need one button graphic to be designed, the button should contain the text 'prophet' and be as a png so that I can still edit the text in order to create the other buttons. I have attached a file of a quick mockup that i did, i am not a designer so its not that good just done quickly but it shows that i want a background and buttons. This is not an exact design that you should stick to but there must be an area to fit a minimum of 12 buttons around whatever design you decide.
