Most Cost Effective Cold Calling Tactic?

[Account Closed]

I've been cold calling homeowners with Property Radar for about 1.5 years. So far its gone fairly well. Lately however I've been thinking about how I could improve the process. Property Radar is good but its sort of slow. I was using Mojo triple line dialer for a few months which actually worked pretty well but I thought it was too expensive to have to keep pulling new lists for it. I also didn't like how I couldn't easily shift the criteria I was calling like with Property Radar. We breifly hired a caller living outside the country and that didn't go well. I'm looking for advice from other people who cold call heavily as their main way of getting business. What do you think is the most effective way to do this? Is it worth it just to pull lists and put them in an auto dialer? For reference my property radar sub is around $950 a year.
