Advice/input on doing a field trial

[Hoff's BigGameHounds]

Hey guys, I'm thinking of putting on my own field trial and water race, maybe even a regular or annual thing.... I need input, and advice on things such as insurance, entry fee, money split, and ext.
I know I've seen a few things at the local field trials that I would like to change... This will be held for tree dogs! Not greyhounds. And hopefully pay out good to the top dogs with a little something to the winners of lower divisions. And make it a very fun event with a band and bonfire at night

Thank you
