Floor sanders and refinishers advertise in the Yellow Pages under the listing" Floor Laying, Refinishing and Resurfacing". Look for a company that advertises that they specialize in repair and refinishing work, not new floor installations.
The best way to find a professional is to see his work in a house and get a direct referral from someone you trust. Look around your neighborhood and when you see a floor refinisher's truck in front of a house, go directly to the homeowner and ask for a reference. Or ask the refinisher to come to your house and give you an estimate.
