I put out about 3,000 flyers so far this year and I got about 4 jobs from them. I get a better return on putting up the pull tab type flyers in supermarkets and convenience stores. Of course the referrals are the best because you already have an "In"... I figure that if I get 1 job out of every 1,000 flyers I put out that it covers my cost of flyers and bags. Then if I get any more than that it helps my profit margin.
