Finding phone numbers

[Reginald Vickers]

I am getting names from tax records of people who are selling their homes. I have used whitepages.com and have even signed up with Spokeo and Intelius to get phone numbers. What I really want to find is cell phone numbers of homeowners. And these services seem to be pretty inconsistent. Does anyone know the best place to find cell phone numbers of property owners?

thanks,

Reggie
