Well, I attend a table tennis club and structure works like this:
Members pay a monthly fee - $10
Non-Members who come to play on the night pay $2 a night
Mini-Tournaments can be held with a $10 singles and $10 doubles prize with a $2 entrance fee - the club has a regular attendance of around 10 to 15 people.
Large sanctioned tournaments are held 4-6 times a year, with a $25 to $40 entrance fee and $250 prize money. People from other clubs attend these tournaments too so we have about 20-35 people on average.
I agree with my fellow South African (rooperi) that you should have a leadership structure within your club - at the very least have a President, Vice-President, and Treasurer.
Running a club is hard work :)
Speaking the TRUTH! There should be a guide for all of this! And It should be called: " The lazy persons guide on fundraising in a chess club!"
