You appear surprised that no one is taking you up on your generous work offer.
On your advice, Kevin, I opened a Thread entitled "How many of us feel comfortable cleaning or polishing a Stone Floor", you may have seen it?
Over 300 people read it, there were 26 replies of which 2 or 3 admitted to being able to do the work.
I hope I dont offend when I suggest to you..
Maybe, instead of advertising/offering work, you would do better targetting people to attend your course?
They could then take the work from you, in a similar way that the Tile Doctor works.
I for one would be very interested in any work, nationwide, but the type of work that is on offer demands a serious machine such as a Levigehtor and until then, I have to decline as I simply cannot afford the outlay....do you do credit?

I was shocked at the floor, cappacino I think it was, the lippage of 4mm is a disgrace and your view of making a silk purse from a sows ear was never more fitting!
The fitter of that floor should be shot!
In my opinion, only a Levighetor or similar, would be capable of such stock removal, you are obviously too busy to travel to do the work?
I hope this message sounds ok, as I have been accused of sounding aggressive on a previous thread, it is not my intention to offend anyone or sound aggressive.
