How much money would you be willing to spend if you could go from regularly shooting in the low 90s to the high 70s? $1k, $5k, $10k+?

Just a hypothetical question I have been thinking about lately. A lot of us spend so much money on gear and lessons and all the stuff. If you could just give some imaginary person a chunk of money to drop 15 strokes, how much would you be willing to spend?
