be confident,and dont be nervous,speak clearly and politely.
Ignore all the "door to door SALES F-off etc"
Remember you ARENT selling anything,merely offering a service.
I went out last night and most who said no said- "thanks for asking"
All i say is exactly this...(I picked up 7 new ones between 6 and half 7 by the way..)
" Hello,sorry to bother you,do you need a window cleaner?"
Now there will be 3 types of response...
"Yes"= "ok could i take a quick look round back to give a price?" (aslong as you are resonable its in the bag)
"No/No i have one already"= "could i leave a leaflet incase you ever do/incase he stops coming"
"..err..pause....." =Ask if they want a price while your there and if they want them doing/think about it and leave a leaflet.
End all the above with "thanks very much for you time"
Always say please and thank you,they will remember you for being polite,and always close any gates,even if they were open!!
Good luck!
