Hi, I was on the forum looking for the same thing!

http://i54.tinypic.com/s1kgmc.jpg\"> I've heard about The Art Circle - they're art instructors in my son's school and he comes back to tell me what he's learnt with them. I was really impressed when he came home with this drawing one day, considering he's 10, and has never really drawn anything before! It seems that have been working primarily in schools, but they're going to start classes at their private studio next year (because of parental demand!). You can try googling them?
