From what I have read, you get a low response from flyers, about 1 or 2 percent. A search on this site will reveal a bunch of threads on this subject. I can't believe it, I've turned into one of those "do a search" people. To make up for it, I'll do the search for you. Here ya go. Have fun reading all day. 424 results.
For what it's worth, I plan to try flyers next spring, targeting neighborhoods where I want to work. I think I can do better than the usual 1 or 2 percent, I hope so at least.
Crawdad, fixin to go mow in the rain, it sure beats the dust of last month....
