I know its been kicked around alot, but I thought I'd share what I'm seeing. After going door to door and putting out fliers, I seem to get the average 1-4 calls per hundred. About 7-8 months ago I started going door to door and leaving business cards. I still seem to get the same response in the week following. What I am seeing now is that more people must keep the cards over the fliers. Maybe they put them on their refrigerator, but they're calling months down the road for service. I found a good supplier for business card stock $6.00 for a 1000 cards, which I build on the computer.
