Exploitive or offensive to you?

So our sportsmen's club is hosting the 49th annual All Breed Invitational winners trial in April of this year. The costs associated with this event is almost staggering. We are fundraising now to generate revenue to help under write the event. I am thinking of banding each bird the day of the trial with some sort of commemorative band, numbered 001- to however many birds we plant during the trial (# dogs entered X 2 birds per dog). I'm thinking about $20.00 bucks per person to enter the "bird band contest". The night of the banquet, we'll pull a number out of a drum. Provided you entered the game and your name is on the list, whoever shot the bird with the winning drawn band number will win the prize. I'm leaning towards a top of the line GoPro camera set up or nice compact handgun.. Does anyone find this offensive in any way? I know South Dakota has done a Million Dollar type game for bagging the banded bird. If you were involved with this event, would you want to take part in this type of raffle game? Just looking for some feed back. No one has ever tried this type of band game before.
