Looking for some T-shirts or bright aprons!

Every year, in April, I organise bus trips (8 on a Saturday) for inner city youth, recent immigrants/refugees, and low income families to study and enjoy the huge snow goose migration through our area here in Edmonton Alberta. Funds are limited and I am looking for some t-shirts or aprons for those volunteers in the lunch area. Up to 350 kids every year!
If your logo is on them that is fine with me and I would require about 6 or 7. Can any Beserker help me out? The event is non-profit and this is our 18th year!

Much appreciated.
