I work in the West Midlands area, mainly in Quinton, Harborne, Bearwood, Blackheath etc. I often canvass door to door but for the most part while doing that I don't get any response. Maybe it is because I usually do it during the day but even when I did some evening canvassing things did not improve. The other way I canvass is by posting cards through peoples doors but it is rare for me to get a call back. If I do then they usually reject me when I give them a quote.
The only way I gain customers really is if someone approaches me while I am working on an exsisting job but even that doesn't happen very often. I also have to drop customers every so often because they don't pay me.
