Starting 2007, I built my round on 10,000 leaflets. 6000 posted by me and the rest by monthly local mag, but not inside it. I was the only leaflet. Maybe you do only get 50 custys, at least 100 I would think with good leaflets, but among them will be at least 4 or 5 serial introducers. One good one will get you five or so of his friends, then you will pick up a few neighbours etc etc. It will become like a snowball rolling down a hill, getting bigger all the time. I have a small £20 ad in local monthly magazine, I pick up maybe 20 jobs a year from it directly plus neighbours, friends etc of new custys After a year you will have plenty of custys. Whenever I have canvassed in the past, I have found the custys don't last that long. My leaflets were all A5, very good quality, colour, with landline tel and address.
