first time i have tried it, i use to knock a area every nite, till i got a yes or no from them if no one was in, and had a pretty good responce, had about 90 custy in first month, but am finding that i dont have enought time to get out knocking now, so am going to get flyers delivered, if i get 10000 over the next 6 months and i get 100 new custy that will do me,
