So hopefully this is one more thing that easy modding can help. There is a modifiable piece of code:
key "GlobalGoldValueMultiplier","0.5"
This changes the global prices of items. I'm not sure if this effects how much gold you find, though. If this doesn't, you could simply increase the multiplier to make the prices as high as you want for your taste. If it does effect the amount of gold you find, though, it's not particularly useful, imo, and modifying the economy would require a bit more work.
