Briefly mentioned on here was race night, our club does this once a year and it generates a good bit of revenue.
You can hire a guy who already has the races, projector screen and takes the bets etc etc.
We do it as following:
Get individuals to sponsor a horse for say £5, 6 horses in a race = £36/race. (they name the horse, the winning horse 'owner' gets a cheap bottle of bubbly.
Get a company to sponsor the race for £50.
We split the race takings 50/50 with the "racetrak man" after payouts, which are managed as a percentage of bets received, and then split between those who had the winning horse.
Bets are placed before the video is selected, this gets around gambling licences. There are no odds, so people place a bet based on the horse name.
Plus takings at the bar it's a fun evening, ticket funds you can raise £1k having a great time.
I have an old racecard at home if someone wanted an example of this.
N.B. This is a great fundraising day for the club, which only has the 1 senior sunday team.
