I know an artist, to call him just an engraver is an understatement, but outside of a select few, I doubt the public at large will ever see his work, he's strictly word of mouth and if someone he knows, broadcast's his whereabouts, say in a forum like this, you had better never darken his door ever again and unless someone he has done work for, introduces you to him and he finds you worthy of his interest, sorry that is it.
I got to know him thru my dad and I have never asked him to do any work for me, if he offer's to do something for me, then I will bring an old browning 1903 I own and see if it is suitable for him to work on.
He feels that you or your project must be worthy of his skill and talent, if he does not feel that he can bring his best to the proposed project or it doesn't meet his high standards, he will not even take it on.
His words on the subject of commercial gain and turning down work.
"I am not in it for commercial gain, I am in it for the pleasure of creating the most beautiful piece of functional art that mortal hands can accomplish."
Then he also has a life outside of smithing and engraving and likes to hunt and fish, just as much as the rest of us.
When dealing with a skilled artisan, patience and courtesy are a must, they know their worth and getting irritated with them, gains you nothing.
