Geoff, how little you know of these type of houses. There are companies who provide people to do maintainence in and outside of the properties, it is they who I show what to do with the machine. .....For some offices I am asked to do I supply a complete set up, portable of course, as they do not want to pay what I charge, which is good because I dont do offices, they then look after the property themselves. Hmmmmm I have supplied 17 machines in all last year and charge 500 to do it. you do the adding up!!!!!!!!........... In answer to a previuos post, if you have a problem with 300 a yard what do you think of 6 and 700? Ohhhh and how about those who have custom carpets made to measure that just costs thousands. I feel we are charging what you dont think we are, on carpets you dont think exist...... Mind you we charge a pound a foot to clean 300 a yard carpet....... you charge at least i hope you do, 50p a foot on what? 50 pound a yard carpet, that being the case you are charging way more than we are...... so therefore what is a pound and maybe 75p a foot to protect a carpet that has just cost if we say 100 yards that would be 30,000 pounds my guess is you dont see 30,000 pounds of carpet in a week. If you do and again I hope you do then wouldnt it be fair for us to charge in a day what you charge in a week, you know it makes sense.....Please note with all this banter back and forth, wouldnt you really want to charge a pound a foot? If so, why knock us for doing what you cant,wont or dont do....... Best, Dave.
