For Example:
Just focus on FB for July
Fill the box with things that are "custom made" just for this/and or players and coaches, limited quantities
Have one item custom made for the each state
Then make them available to buy after the first one in limited quantities say 50-100/state.
Make the price equal to the cost, plus shipping, plus a $500-$1K donation.
I know it isn't that much, but it could offset the entire cost of the project
Oh and then do it again for BB and then for Spring sports...smaller quantities, cheaper prices
