Duvall's have pretty much quit doing schools, you may be able to get them to do a private clinic at the rate of $300 a day if they've got time (this is what I was told when I called them at the begining of the summer) and it seems they no longer have an active website??? Not one that I could find anyway.

I apologize...did not hear that they stopped putting on schools, and I noticed that they took the website down after I had already posted. Should have checked first I guess. Good luck, and will re-post if I hear of anything.
