Not sure if this will throw a spanner in the works, but I recently had some shirts made for a club event I'm involved in. They were T-shirts, printed one colour, front and back. We had a darkish blue shirt with white print, and a grey shirt with black print. They came up really well, and the quality of the shirts was excellent. So far there have been no complaints on washing etc etc (touches wood)
The best bit was they only cost us $10 per shirt + freight.
So I'm not sure if you guys had someone in mind or not, or if you're interested in a front and back design... please feel free to tell me to piss off if I'm making trouble here... not my intention.
