Well if you want a scope, you either have to be able to drill and tap your self (money for a drill jig & drill press), have a mill and the know-how to do it, or take it to someone that can do it. Just saying.
The very first rifle that I built was a standard 284 Win on a Turkish Mauser large ring action with small ring threads. By the time I got done drilling and tapping, having a new bolt handle welded on, buying a new stock and barrel, buying a reamer and head space gauges, replacing the firing pin, safety and trigger and doing all the bedding work, opening the feed rails for the fatter cartridge, I could have bought a 700 and been done.....again, just saying.
From my point of view, I would recommend selling what you have and buying a rifle....but that's just me.
