best rollerski T-shirt design?

I am thinking of designing a T-shirt which I would wear while
rollerskiing, saying smth like "This is called rollerskiing". This Sat
was the first nice spring day in NJ; my fiance and myself were
rollerskiing at a popular bike path, and have been asked at least 10
times. Not that we mind, but we figured it would be cool to have
self-explanatory slogans on our tshirts.

Does anyone know a company that would make custom lycra shirts for a
reasonable price? BTW, "This is rollerskiing" shirts could be smth for
Jeff Potter's OTB site to add to its inventory.
