I have priced out custom stocks and the prices cause a person to shudder (think fixed income).
Call it "semi-custom" but I used Wenigs for my Mauser (
http://wenig.com) and found then pretty reasonable. It was upgraded to extra fancy Claro with the recoil pad and bedded. My gunsmith found zero issues with it. The stock was $1400 and another $300 for the Mannlicher style. All in it was $1800. Not a trivial amount of money but I doubt I'll ever do another. custom and I smile every time I handle it.
I'd call Leasa there and asked what they have. Perhaps they can sell you an inletted and rough blank to finish?
