I thought Ians 2 to 3 cleans price fair.
Mick, so who being taken for a mug, you want to pay 1 to 1.5 cleans, but what would you sell the round for
6 to 8 times or 8 to 10 times whos the mug ? 
No i wouldnt pay 1-1.5 cleans id pay £5 per customer and no more.
Fact is canvassers canvassing for others doing it as there business will sign up any old crap and charge 2 cleans plus for it. Name a respectable canvassing company who have been going more than a year by keeping there promises and not letting people down???.
If buying established work then happy days id pay upto 4 cleans for it but for canvassed work no chance as its mostly poo unless you do it for yourself so can pick and choose roads and areas. So who's the mug you say?? well it defo isnt me my friend. I wouldnt get 1k canvassed and payout 2k for it to find 50 percent will dropout after the 2-4th clean meaning the canvassed work would end up costing 4/5 cleans in the long run...no way pedro!.
My point being that all so called canvassing companies are chancers waiting for there willing victims. Maybe my view is ott but it was how i felt about people when i canvassed for them so personal experiance saying how it is.
