RM if the action will accommodate it, you might be able to capitalize on the 26 Nosler craze.
In general custom rifles are a very personal thing. If a person is going to pay the money to go custom, they might as well get EXACTLY what they want, and not buy what someone else made.
Last time I bought a custom rifle it was unfired and I paid about 1/3 what it would of cost to make.
