Directory distribution, Any Good?

A question about : Directory distribution, Any Good?

There is an advert in my local paper for directory distributors for the yellow Pages, just for a few days.

Has anyone done this work before? Is it worth doing or not particularly rewarding? what pitfalls?
I know you need a car, phone etc
TIA

Best answers:

• I don't actually know what the return is on delivering Yellow Pages.
  But I have noticed that it is a different lot of people that do it each time. I suspect that if it was any good, the chap with the contract would want to retain it. I live in a rural area with a low population density and not very good road signs or house numbering/naming, it's not needed as everyone knows everyone but this doesn't help the delivery chaps. Might be a different story in towns.
• Hi I've passed the link to someone that has experience - it could be that this ad yuo've seen is from a distributor rather than from yellow pages themselves
