Hi, as part of a deep clean we are doing in a restaurant, they need a varnished wood floor that meets a grey quarry type tiled area, cleaned. Altogether approx 50sq metres. With the tiles taking up about 75 % of the floor. I was thinking a light scrub with buffer then polish with buffer. What do you think a competitive quote would be, in the north west, and any advice on the cleaning of it would be appreciated, as this is something that's new to us. Thanks... Darren
