Just a suggestion... take a look at these two Bearcat uniforms. If you don't have software that can swap out colors to make it what you need, try PMing the creators. They are both veterans of the boards and may accommodate. Also, take a look at the Stickies and consider trying the web-based uniform/cap creators or justafan's software for it. Once you have a .png file, you can work with customizing it as a uni or cap element.
