Jury barrel: 425 bucks
Corlanes install: 350 for weird calibers
Pillar bedding: 150
Blueing or cerakote: 200-300
Aftermarket or trigger tuning: 150-350 with install/ various brands
Case hardening, stock work etc: not budget by any stretch of the imagination, especially if you use an experienced artisan like Flach, martini etc ( no shade on anyone else mentioned these guys are specialists and in another league)
Realizing that you get can buy someone else’s custom on the e.e for less than these gunsmith fees: priceless
The good thing about Mausers is you can buy rifles that have what would cost literally thousands of dollars in smithing fees for under 1k and usually under 500 bucks on the e.e.
I would start on a p-hale or old sporterized reciever to save money. Zastava builds for non giants will require a reduction in LOP and a new non hockey puck pad. I think the last time I had this done with bedding it was ~350 bucks. They do have good, adjustable triggers which is a budget consideration. Adjust it yourself or they may charge you for a trigger job on it, ask me how I know. Very simple
We are verging into the realm of personal opinion here but zastavas come in hogs back stocks that will amplify recoil or raised comb stocks that are uglier than hell and do not work well with irons ( for me at least, but I’m no giraffe, more of a gorilla)
There’s a RMR 404 Jeff on the EE for a more than reasonable price or was, I’d check that out
