One of the ways would be to create an account that people can pay directly into and set up a monthly figure for example as a direct debit to enable a fixed amount per month.

Some homework is required to get the actual figure needed per annum and then see how many people are prepared to contribute on a fixed monthly basis.

I really do not see a problem because this community is more valuable to end user than i have ever seen before, anyone can come with a question and within minutes get answers, that makes it valuable, just think of the phone cost per problem to helplines etc if we did not have this help readily available on here.
