Looking for Outbound Cold Call Service

[David Flanders]

Good afternoon. I'm looking for an outbound call service - basically a service that can make cold calls to lists of potential sellers (ultimately for wholesale purposes). What company do you use that are the most effective? What companies should I stay away from? Looking only for companies that specialize in calls to gauge owner interest in selling. Would be nice if there is flexibility in working through the "script" with them, but not required if they are experts. Thank you all!
