I would like to start one in my local area where there isn't much provision. However I don't want to go down the stage coach route where classes are very expensive and therefor exclude lots of people, at the same time I need to be able to pay myself.
Is there a way to do this so I could maybe apply for funding to make it cheaper? Or perhaps provide bursaries? Is there a place where I can get advice, I don't know where to start with the business side of things to be honest. I wondered about something like a social enterprise.
I would start by looking at the Arts Council for funding. You could also seek advice from Business Link (which I think is part of the Chamber of Commerce). Often funding is more forthcoming if you are doing something that benefits people with some kind of difficulty (financial / disability / access issues / etc). I'm sure that those places could then point you in the right direction.
And if you have links with drama schools / theatres / etc, perhaps you could find a way to work with them?
