Start-up: Have you surveyed your local community/city? Better there than here because there maybe other related facilities or none. We're just a bunch of people from all over the world, giving feedback.

But in the end, it is best to partner with local college art school, your municipality (who runs the community centres), to find out the limits of their facilities.

I think if it's run as a non-profit co-op with a board that's elected and some membership fees, it might be safest model. The reality is, is to combine it with artists who teach courses that require the same equipment and supplies.
