Need Help for a White Page Type Program to get Phone Numbers!

I am looking for a White Page type program to get Phone Numbers

I have the address of the various properties now I need a web program to get the Phone Numbers. I was wondering what most of you use and what pros & cons you could share with me.

I do not want to spend whatever 411 charges for every call. Also I do not want to sit in the library getting the Yellow Pages and copying out numbers. I would appreciate any help you could provide me with this.

I am also a bit mistrustful of the ones that want to charge me per individual phone number. Where am I going wrong? I have been on Google to get  FREE look ups and they always say “can’t find number” but go to affiliate and for $ we will give you the number…

Thank you in advance for the help.
