My son has the best ever way I've seen of door knocking,
He takes about 10 leaflets on top of a presentation folder up to the door of the property in mind, knocks on door. says something like "good morning, sorry to bother you , but we've paid a distribution company to deliver these, and I'm just checking they were deliverd"? (as they didn't the victim says no as she's looking at the flyer in his hand) Then he says " this is what we specialise in, would you be interested in a quote" He used to get me plenty work but as he has is own very lucrative business now and I haven't got the bottle I just leaflet. But this is not perfect by any means, but I tend to get referals from jobs Iv'e done
