Cleewindows, pay one good canvasser decent money, with two muppets you'll just double the ammount of aggravation. You want to grow, but you dont want to pay. Maybe look for a more realistic method of growing customers.
So you want a canvasser to go out and knock, find you good priced work , say a small semi at £15 done 4 weekly ie £180 a year. And you will pay £7.50 after youve cleaned it, then another £3.75 a month later?? Who with half a brain would stand for that?
But good luck.
