Having a takedown tournament on a Friday night before a kids tournament where the proceeds go this fund is my next suggestion.
I know the schedule is already jammed packed so maybe something on a Friday night. Find a club where everything is already set up and maybe get some refs that might be willing to donate some time. Get a few clubs in the area willing to donate some table workers.
Couple hundred kids should raise a few thousand dollars after medal expenses.
Maybe charge everyone $2 to get in (it is for charity), there another $500 to $800.
Let the club run a concession stand for their time.
Do a few of these through out the year is $10k
Plus its good mat time!
But this would take a lot of people to step up and be very selfless!
