you can go to the FEGA , "Firearms Engraving Guild of America " and look and see if they have a member in your area
OR you make a post one of the main engraving forums like Steve Lindsay’s engraving forum
http://www.engravingforum.com/forumdisplay.php?f=2
or over on the Engravers Cafe
http://www.engraverscafe.com/
either of the 3 places should be able to give you a connection to someone in your area or across the US and over seas
