oh obviously if 1000 people were willing to pay $10 then it'd be a good idea.
Balancing financials would be one of your goals after all.
I mean if 100 people turn up to watch Lower Hutt v Upper Hutt for free, or 10 people turn up paying $10 - then as a community football club maybe those extra 90 people would be better than the extra $100.
As I said, depends on your goals and the costs/benefits of each option.
