One piece of advise I can give you to help your turn out is get out and get donations for the prize money. Then you can put on your flyers that the money is guaranteed. Then your group or organization can keep all the entry fees. Because the minute some anglers hear that all the money is not being paid out they look for something else to fish. But if the money is guaranteed they will show. Also it is easier to get donations if some of your guys just go around to local businesses and ask for donations for your group. And I mean ASK EVERYONE you will be surprised who will give . Banks, lawyers, local co-op, funeral homes ,gas stations resturants ect , you get the picture .
Good luck
