WOW!!! You're right he is VERY talented! I had a friend in Phoenix who was a Navajo artist whose works graced many lobbies and offices in the downtown area. The Heard Museum (for American Indian artists) used to market them for him.
My dentist there (who was a dentist at Ahn Ke in Nam) used to show his wife's art in his office and waiting room. She too was talented- she painted many seascapes- people used to buy them from there, so you may be on to something.
It seems to be quite a popular way to show your work!
