We bring in about £4k a year in sponsorship, £4k from fund-raising events, and maybe £2k from subscriptions and match fees. But we're just a relatively small club with 2 adult teams and a small handful of volunteers, a bigger club should be able to raise proportionately more.
Sadly it doesn't work like that. We are based in a semi-rural location so no matter how big we are as a club - and we share a small geographical area with a couple of very large teams with benefactors who can bank roll hefty player budgets - there are a finite number of businesses that we can tap into. Add to that a changing world where value for money in marketing spend points to online advertising. This is what Blackpool CC, a large club who host Lancashire fixtures and get sufficient crowds to charge for entrance, look to bring in:

As a general point, the fees involved in playing cricket are very modest compared to other sports. The hockey and rugby clubs around us all charge significantly more than the cricket clubs in the area.
