This is all you need
1- Knock all houses on junctions, cross roads, end of streets, why- more public notice for you
2- its all about the presence of being there, have the best van you can find and wash it everyday
3- Have a nice uniform and polished boots -hi tech magnums
4- customers are always right
5- tell them how nice there garden is or there car etc
6- Always smile because if they look out of the window and see a sad man that makes them feel unhappy, your happy there happy
7- Always have a shower in the morning and shave
8- If they need a chat -A chat it will go along way
9- Also think that every customers house is the queen and you have to do the best possible ( YOU ARE ONLY AS GOOD AS YOUR LAST JOB AND DONT RUSH IT )
Hope this helps
