Ringo, try to keep positive there will be hundreds of custy's out there for you, you just have to find them!
when you go out - look smart, be polite and if poss have a flyer with address and HOme phone number - mobile makes you look iffy - people like to know you are genuine ( print your own flyer from your PC )
When canvassing dont pre judge the road area - my very 1st day i didn't pick up anyone in the first 5 roads - all had w/c or no thanks, turned the corner and bang nearly every house wanted one - and it looked pretty much the same as the previous road.
smart or dirty every house is a potential new custy.
good luck
