FD, just get yourself on an airplane to Eastern Europe and get it recorded by professional musicians. Lots of studios are doing that on a budget.
50K at most.
Add it as a retroactive stretch goal, should have been hit about half a year ago.
Who's to say that's not the plan already...they don't need "strech goals" for that. Actually, they don't even need to get on a plane for that since several orchestras can do recording sessions like this over the internet anyway.
