Susan, you may privately consider yourself a student, but you SHOULDN'T be presenting yourself as one. You have your own sound equipment, apparently some well-developed programmes, and tons of experience. You are the Artist.

I live in a rural area not unlike your own (national differences aside), and our little podunk community arts centre pays the standard Ontario Arts Council per diem for visiting artists to put on a workshop. Actually the per diem by the book is $250 Cdn/day plus travel expenses. We budget that when applying for a grant to do something or other, for non-grant-funded workshops which are paid for by the participants, we usually pay $200 + travel. (Attendees usually pay $20-30 plus materials costs if any, for a 4-6 hour workshop). These might be musical or any other type of artists, what they have in common is that they bring both their talent and equipment and share it with others in a hands-on educational/participatory fashion.

Your mileage may vary...
