Corel Painter Tutorial

I am looking for a person to provide tutorials on use of Corel Painter. The right person for this task lives, eats, and sleeps the software product made by Corel named Painter. I am NOT looking for a Photoshop expert. I am NOT looking for a graphic arts designer. I am looking for someone who is expert in this specific tool. I would like to see a portfolio of original paintings you have created in Painter, as this will give me some sense of your style. I am particularly interested in finding artists who are good at using heavy brushes in an impressionist style.
