Who here has done it? How do you think it worked for you? I mean where you go up to the door knock and try to sell your service. I never have tried it, but today sombody tried it on me today. Thought it was a really good idea. It is a way to get your foot in the door at least and just give them an estimate at least to hold on to, could say its good for 90 days or somthing along those lines. Thought this would increase the success rate.
