[Build-It-Break-it]

I would imagine about 6 digits $$ parts and labor for builds of that level. The crazier you get the more you pay obviously. Most places charge $85hr shop rate. Just an example: Mini tubs will cost you $350 for parts but 40hrs of shop labor ($3400) to put them in. Last I heard that's the amount of hours they charge for that particular job. Do the math, it'll add up fast.
