i do tile for a living and i know a few hardwood guys that i would NOT recommend. but seriously just get some quotes from reputable companys. you dont want some yahoos working in your house and burning it down or something like that. of course you could always just find someone willing to do the work...thats all it ever comes out to with construction....but you cant compare some guy at the homedepot and a company that is licensed and insured. thats comparing apples to oranges in price range. depending on what you have in the house it could be very easy or very time consuming covering and moving stuff.....it sounds like the house is empty and that would make it easy to just sand it,clean,stain/varnish whatever.
