Ian , sorry for not answering sooner, Its simple.
1) put your name & address on it and only have them delivered within 4 miles of your home
2) put testimonials on it from local companies not individuals ( people will think you made them up if they don't reconise the name)
3)have them delivered to the same house every 4 weeks, for ever
4) give a retired person discount
50% of my customer are OAPs, they live in bungalows, and the carpet don't get a lot of foottraffic or bad stains so they are usually an easy clean
5)FULL COLOUR WON'T MAKE A CRAP LEAFLET GOOD!!
use a well designed one colour leaflet, it will pull in as much work as a full colour
these 5 pionts are just my opinion
