i started off with just leafletting.
I once leafletted on a sunday, posted about 50 leaflets, and got 2 calls later the same evening.
Now i rely on door-knocking, if nobody is in i post a leaflet, and knock back if the windows look dirty
I usually door knock during the day, weekdays & saturdays. But with the lighter nights coming i am going to try knocking from 6PM till dark.
