Simbo,
I bet you've leafletted places and had two or three phone calls from one area and, if you've asked, I bet the potential customer would've told you that they haven't seen their old window cleaner in months.
That's the place to canvass.
Try it. I find that because I'm not desperate for work, sometimes I'll do it for fun, rather than clean windows. The last time I canvassed was during a really hot hot day a couple of weeks ago.
It was just too hot to work, so I thought I'd go door knocking, rather than waste a day (shopping or something with Wor Lass).
Wor Lass leafletted - she also won't door knock - so we split up) and in a couple of hours I got a £35 house at EOM, an £18 house monthly and a £12 house monthly (it is a posh area).
Anyone who wasn't in received a leaflet (my leaflet needs updating mind), and I haven't had one single call from these; though I know for a fact a window cleaner has dropped out of the area.
Just don't look or act like a Chav; be polite; and as the guys say, it's a numbers game.
Try it. The worst thing that can possibly happen to you is that someone is so cross that you've disturbed them, that they physically attack you.
But I think it's rare this happens.
