Wanting to know how much to charge for a office that is 3210 sq. ft. This would include sweeping, Mopping, Vacuuming, emptying wastebaskets an Detail dusting such as desks (around 40-50 of them) Computer screens, cords. 2 stall men's and woman's restroom a decently sized kitchen/break area. Any input would be greatly appreciated.

Figure all your costs and then add a profit factor. In every area, competition drives pricing.
