Thank you guys. See, it wasn't that exciting was it?!

Sherwood - Thank you, that is very helpful.

Bonnie Blue - sorry, I didn't explain properly. I'm thinking of setting up a company which would distribute leaflets for other businesses. I am not looking to use a distribution service for myself.

My thinking behind trying to get road names and number of properties is that I would have to employ distributors. So, for example, if a company asked me to distribute 1000 leaflets I could hand them over to distributor "x" with a list of road names that would contain a minimum of 1000 letterboxes.
