[Organizers] guarantee/profit sharing?

Hi all! Writing in my role as an organizer of the new second Saturday Montpelier Contra Exchange series: http://www.contraexchange.org/. We are trying to figure out a band/caller payment amount that works for both us and the talent. So — simple question: How much to do pay your musicians and caller? Do you have a guarantee, and if so, is it per person or for everyone, no matter the band size? Do you do profit sharing on top of that? (I will say that the well-established Montpelier dance on first and third Saturdays, which I also help organize, has a guarantee of $650 to be split among musicians and caller, with additional payment for sound. We share additional profit based on attendance, once our expenses are paid for and some money saved back for dances we need to subsidize.) Thanks!
