Like just for one would cost that much
I think you're missing the point. "Just for one" makes it even worse.
Manufacturing is based on volumes. Not only would you have to get a schematic for the board, you'd have to find someone with the equipment willing to divert it to make one for you, acquire the materials....
As above, probably several thousand dollars, at minimum. Your best option is trying to find a refurb board or units being sold as "non-working, for parts" on eBay. If you're talking about making a board that would take a new socket but fit in your current chassis..... that's not happening. Simple as that.
