not to be a wet blanket
but
the community, has held more then it's fair share of fund raisers
for the mentally challenged
life threatening medical conditions
for someone who's house burnt down
and others
there are so many people asking for our charity dollars, that one must pick and choose the best or most important to them needy cause...
I really don't know how much support you will get....IMHO.....
but that being said
you need to find a location and date to hold it, you need to know what can be caught in that location at that time of year
you need to make sure there is no other events on the same date that will take people away form you event...
you make sure there is access and parking and a place to take a pee
then you start finding prizes, hit the tackle store or better yet find people who have a connection to the tackle stores
find a food company that will give you the food or a great deal on it.....
if you can get a local fishing club or other type of club helping you are ahead of the game
and that is just to get the ball rolling
