There is a new approach to solve this problem. An application called Rovas allows you to go the middle way; make a payment mandatory, but allow people to pay with their own volunteer time. This way you will not exclude anybody and folks who do not want to (report) volunteer work, can still pay you in national currency (experience so far suggests, that most do).
