you need to put out 4-5k a week rotated monthly, so if you live in a large populated area this could be within 4 miles of your home, if you live i the county then this could be 15miles.
people prefer to use local tradesmen so to deliver as close to your home as possible makes sense, ( make sure you have your address on your leaflet) The bigger area you cover the more time you spend driving betreen jobs.
