Just a small tip on canvassing,we used this many years ago and it should be same now.When you get a new client on a street the next call sould be,hello mrs a has asked us to clean her windows and we just wondered if any one else required our services while we are here,then if you get that one it s ,hello mrs a and mrs b has asked etc etc .It s surprising how this persuades anyone who don t like setting strangers to give you a chance. cheers mick
