Sorry, I don't mean to be defensive. I have spent the better part of two years researching on this forum and taking notes from you all here who are wiser, more experienced than I in this area.
I simply see nothing to lose and no potential drawbacks even proposed. As I said, if I was trying to build an operation on the scale of the Giants here, I would be more likely to agree. As of now I'd be content with a mere 1000-1500 per week in business, a goal I feel ten hours per week door knocking will provide, at least to start.
For brand visibility? Flyers are probably better than knocking, but there are alternatives better still. For getting business and giving estimates, especially in a area with such a limited population as mine? Door to door just seems a better match. I could be wrong though, in which case no big deal. Perhaps in that case a mix of flyers and knocking would be appropriate.
