I have used flyers since the get-go. On those days that I fall short of my revenue goal, I still put out 1 flyer/day for every dollar short I fall that day of my goal, e.g. if I'm $89 short I don't let myself come in until I put out 89 flyers (weather permitting). I have always used black text on white paper. I have found that an actual price offer, e.g. "2 rooms and hall for $xx.00 up to x-hundred total sq ft" pulls better than %-off offers. I put the flyers at the front door. Lots of text and explanation pulls better than sparse flyers with BIG TYPE NO SUBSTANCE. My flyer is two sided, 8.5x11 covered with 12 point type. I do not put expiration dates on my offers. I place a flyer with fridge magnet five-around after every job.
