best thing to do mate is canvass a few days after leafleting with your leaflet on your clipboard.potential customers like to see a face to your business and lots of people want a decent reliable window cleaner but forget to ring you or dont seem to get around to it.go and knock on and seal the deal!its tried and tested.i leafleted a full estate of 4 and 5 bedroom houses yesterday and im going canvassing on there all day tomorrow.ill let you know the results!
