I'd be happy to spend some time training.
I started window cleaning upon leaving school in 1986 from canvassing, had a break for a few years and canvassed for double glazing, trained teams of canvassers at the time, sold cable TV, Gas/Electric in the 90's door to door, ended up going back to window cleaning, canvassed my rounds, sold a couple and this year been canvassing for a few window cleaners (for which i can provide references).
I don't give any guarantees (as i think talk is cheap and the proof of the pudding is in the eating), to give you some idea of what i'm capable of last month I got £1850 on a four weekly turn over for one guy in 7 working days, this month £850 for another in 5 working days and currently on target to do the same for another.
I am currently booked up for around another month with repeat business, but be happy to do something for you then. In the mean time if you wish to get in touch for some free advice feel free.
