Re: Would you pay to be trained in stone????
One more thought, on a more positive note. When I was in college, when dinosaurs roamed the earth, the art department had extra funds for guest lecturers. Most guest lecturers were given $500 for a 2-3 day visit.
Might want to try the colleges around you to see if you could be a guest lecturer at the colleges. Then, that might give you a start on teaching more advanced skills in your studio for a fair amount of money. Or take on a paid intern - where the college intern pays you might be another alternative.
Another way to see if you like the teaching gig.
On that note, I will quiet down, go back to work & be a good little artist.
