there are several different price ranges, but you can expect to pay anywhere from twenty five dollars an hour, into about fifty dollars per hour depending where you rent from.
About $80 to rent a floor sander and polyurethane is about $25 a gallon. So depends on how big of an area
A floor sander is really just a heavy duty piece of equipment that you can rent from a home hardware store. That being said if you need to find an operator for this floor sander, any construction worker (you could ask your local hardware store) should be able to use it.
I think more than 50,000
I highly suggest the following: http://business.shop.ebay.com/Floor-Sanders-/56968/i.html, http://www.hardwood-floor-sanders.com/, and http://www.u-sand.com/default.aspx.
Rent a large floor sander, use rough (36 or 48) sandpaper and wear a good mask -it will make lots of dust.
You rent a floor sander from somewhere like Home Depot. They sell different sanding pads to go with them. Get goggles and mask too, this makes a LOT of dust.
The average cost to rent a floor scrubber is anywhere from $500 to $4000. You can compare prices at http://www.costhelper.com/cost/home-garden/refinishing-hardwood-floor.html

Rent a floor sander from Home Depot and remove it all very quickly. -Be sure to wear mask and goggles, it makes a lot of dust you don't want to inhale
Rent? Is that legal?

A sanding machine will give your floors a more even look prior to refinishing. Sanding by hand will take a very long time. You can always rent a sander.
