im not an old boy or at least i dont think i am and for me it is most definately canvassing all the way , that way you are in control of where you are at and you are not waiting for the leafletted custy to phone you
when they get round to iti have benefitted greatly in the past by a local competitor of mine who leafletted this area as i hired canvassers to knock fairly soon after and cleaned up

scenario 1
custy wants a window cleaner and gets a leaflet and says " oh yes i must call that after hoovering cooking dinner taking kids to school etc.
scenario 2
custy wants a window cleaner and me or someone representing me knocks on their door and signs them up there and then.
scenario 1
£x per leaflet £x for delivery = £investment that may or may not come good
scenario 2
£Your time or £commision only for hired canvasser you only pay if they get you work.
Your choose which way you wanna do it but for me it is a no brainer and i have built my business on canvassing alone and in 5 years i have gone from 0 customers to 2000 and 4 vans.
