You might want to look at Tom Turpin's Modern Custom Guns (book):
https://www.amazon.com/Modern-Custo...swatch_0?_encoding=UTF8&qid=&sr=The book lists and gives pictures of many beautiful rifles and skilled artists.
Many I'm not intentionally going to mention below, just short sighted. And you didn't mention a budget so (if you can afford the top two you don't need anything from me!)...

Leroy Barry at Canyon Creek:

Robert Szweda:

You'll also have to purchase a wood blank. That alone could ruin your budget. I have purchased wood blanks from Cecil Fredi in Las Vegas and Roger Vardy in Australia, both with good results.
