I recently inquired about recommendations for stem work and George responded by posting these links to acquaint me with what I was getting into as well as how things are on his end. He charges $25.00 per hour and is likely the best I've ever seen. That is, if I have seen better work, I could not say where or when, if ever. I'm saving my pennies now.
Good luck!!
