One system that seems to work is a discounted membership fee where a

This. The local archery club has a similar system that works with little
friction: The membership fees is discounted, and the paid excess refunded at the
end of the year, if the member does his x hours work.

This also addresses the problem of those physically unable to work, only able to
work at times when there is no work to be done etc.
