This is the estimate for the Las Vegas El Rancho's Tower. $18,182,000. I am not sure that this was the company who built it. This is a detailed estimate.
The second page is the price breakdown for the construction materials, labor, Equipment & Transport, and sub contractors.
Just the Doors & Windows to be purchased and installed were - $1,274,970!
If you collect this kind of thing - email me.
