He's not alone. When we set up our supply business we searched for potential customers in our area. Thats from Berwick upon Tweed down to the south of Durham. We identified around 150 "professional" carpet cleaners. When we added the others that do carpet cleaning it went up to around 400. You'd be amazed at the amount of trades who also do carpet cleaning. The obvious ones like car valeters and window cleaners but also lots of builders, plumbers, maintenance companies etc.
