hiya mate iv used the same canvasser for a while to build up my round and it does build it up but believe me half the work will be rubbish and you will hate it having to go round cleaning peoples window who just dont want them doing regularly.
iv just dumped prob 70+ customers that my canvasser got me for these reasons, iv found from a lot they agreed to one off cleans etc i used to pay at end of the day say he got £100 worth of work id pay £100 too him but then dropped down to 0.75%.
i was gna giv him another go this month but he wanted 0.85% i said i wanted to ring rnd new customers welcome them on board etc n he sh*t himself n backed off. if you use a canvasser try and build up a good rapport get it wrote down what you want from him, things like prices,frequencys, get customers to sign to say they agree to a REGULAR clean (this he wouldnt do!!), other services they would be interested in etc
good luck im going to begin canvassing myself and only take people on who agree to regular 6 weekly service who really do need a cleaner.
