Floor refinishing recommendations

hi, i need my wood floor refinished and stained,
so far we have had a few companies come by and give us quotes.
whats most interesting is what some point out and what others completely ignore or don’t see.

the quotes we have gotten have been from 1500.00 to 5k- which is beyond me why there is such a margin. the one thing i have realized through my reno is that the higher price doesnot mean better quality/service/skill etc.

can anyone recommend some honest craftsmen that take pride in their work?

thanks
