Dunk Tank Rental Sometime This Fall

Hello everyone. I am Chris and I am avolunteer with a group called V-91. V-91 is a community group that does park cleanings, picnics to benefit charities, as well as good deeds for the community. We are all a group of 14 year olds and we are looking at holding a picnic sometime this fall (September, October, or November) and having a dunk tank that the owners as well as myself would get in and the community would dunk us. Now we would probably charge $2 to throw 6 balls at the target to dunk us and mind you we are a non-profitable organization so we don`t have a lot of funds. So we were just wondering is anyone would be willing to let us use their dunk tank sometime in the fall season and they would be willing to give us the lowest price as possible? If anbody could that would be greatly appreciated and remember all of the funds collected go to a charityof the owners choice. Thank you and have a very nice day!!!
