I paid for lists when I came out of the box. Yet, when I ran out of names on a list I paid for, I called names on some old dusty lists I found in a corner that some trainee had left a few years before I went into the business.  No different. So, then I went onto Switchboard.com and I literally queried all the Joneses in my state (serious!). So I called every person in my state that had the last name Jones (my colleagues thought I was joking around- then realized I was asking for Mr. Jones, Mrs. Jones for real. What a hoot!)  Ultimately I learned it's just about volume and consistency.   So really - any list will do. Sure, knowing the age helps, neighborhood helps, home values help - but really - it's about the calls you make and the connections you make. Business calls, residential calls, eventually - you hit. Just put one foot in front of the other.
