I just had a couple of estimates for redoing our driveway and each of them had grinding the old finish off, at $2 to $3.50 per square foot. They did not give the name of the company doing this work, so you could try calling any of the driveway painting/staining companies and ask them for a recommendation. I am guessing you will need to have the garage empty to do this, be sure to ask as the companies I was taking to take no responsibility for moving customers personal property. I had another thread on recommendations for the driveway work and as I recall the company contact info was provided by others.
