I'm not even sure what kind of shirts we are talking about.... Tshirts would be cheapest, of course, but personally, I'd much rather have a classy looking golf-shirt with a nice embroidered logo on it.
I'll email you a logo anyay and see what you can come up with..
If people are interested in a more fancy design, let's see 'em. The person who comes up with the best design would of course get THEIR shirt for free
Anyone who wants a copy of the official logo to work with, email me and I'll send it to you.
