I bought a Jim Chambers Virginia rifle kit. I have the ability to assemble the kit but I am definitely not a professional and do make some mistakes. I have never tried any carving or engraving and am not artistic. I want this gun to be special and done right. I also want some decoration done but not overdone. So my question is what would a fair price (ballpark figure) be for assembly and a medium amount of carving and engraving by an expert gunmaker ?
