Kevin, Sounds like a nice job! First---Just my 2 cents.. A job this size requires a lift called a nuckel-bom it can reach 90-120 ft hi, The price of it in North Carolina for rental is around--$4,500.00 for one week. So include a price for the lift after you find out what it'll coast u.Then figure-- Either by sq ft or by the hr.--Realy depends on u & how much u want to make or how bad u want it.WE would charge about $15,000.00-$18,000.00 for a job this size. Once 4 years ago we gave a bid on the Big Blue Cork-Screw Roller coaster at MYRTLE BEACH (If your familure with the size of it??) THE Price of that job was $20,000.00..... So I guess it's all in what u want $$$$$$$$$$$$$ Good luck & congrats on the kid
