i just spoke to some friends of friends at IndyInk. they have done tons of tshirts for the tattoo shop i go to and are some nice folks. as a ball park #, if we did 100 men's tshirts with one color on the front and one color on the back, they would run $6.65 a piece, $352.45 and for 20 girl shirts one color front and back, they would run $8.35 a piece, $125.25. total project, est. $477.77. the price changes with more colors and larger or smaller quantities. however, the price breaks for quantity are not so great that is worth ordering 500 shirts on an unknown venture.

i don't think as a first run we should order too many more than 100-150 shirts. i'm not sure how many active racers there are, but i am guessing there are not many more than 100-150 and not everyone will buy a shirt. the first batch may go fast, but it is better to have to order more than to have capital sitting idly in a box when it could be used for other projects.
