Looking for a reputable T-Shirt Company for a Charitable Softball Event

Clutchfans -

My state organization is holding a softball charity event benefiting the Houston Food Bank. I need shirts with at least 6 different colors (80 shirts at least) with an optional 4 Letter Logo. I'm looking to pay the least amount as possible so we may donate as much as we can to the Houston Food Bank. If we can get a organization to donate these shirts or pay for the shirts, then my state organization can give all the money we raised to the Food Bank. We take no profit at all and the tournament is all in good fun.

If anyone knows of a reputable low cost T-Shirt company, please advise. If anyone know of any organization that wishes to donate money for shirts or just donate the shirts, let me know. Any questions, let me know. I'd be happy to answer. Any and all help is definitely appreciated.

As state employees, I have to stress that we cannot take any gifts of any kind. All money goes to the food bank.

Thanks Clutchfans!!!
