We at B!KE have been grappling with the question of how to structure payment for our drop-in shop hours. This is our main program and therefore our most consistent income generator. 
Currently we have a $20 annual membership fee, which is great because it's (reasonably) accessible for most, but less great because it's rather inadequate as far as covering our expenses  (we have about 100+ new & renewed memberships each year- not going to cover the bills), and is probably too little to ask for from those who use the shop frequently or those in higher income brackets.

We've discussed two-tiered membership fees (regular and un/underemployed) or workstand rental time. It's really important to us that the use of the space is not out of reach to anyone, but we're also reluctant to have an overt volunteer-as-payment system because we don't yet have the infrastructure for that, and frankly, we do need the cash.

I was checking the google docs spreadsheet to see if it listed different organizations solutions to this, but I don't think this is up there yet. Anyone have any thoughts or suggestions?
