I did a ton of work via the internet and telephone.

Bandit signs on the telephone poles?

However there is a lot of value in the ability to thump someone's chest over a telephone call.

Absolutely within an hour.The bigger issue is two fold.1) having the right script2) understanding things like pacing, mimicking, positive /negative reinforcements, embedded commands and the use of silence.IMHO learning telephone technique is as important as learning how to put a deal together..

On the internet there are sites that you can put in a name & address to do a reverse telephone number search to contact people by phone instead of mail.

Or, hire someone to put them up on wood telephone poles.Good luck!

However I also remember the 1800 dollar telephone bill while out of the county on vacation because I had deals going on and thought I need ed to call my office staff.Can one have a job and a few rentals yes.

I follow up their answer with a favor question to stick by their telephone and I will call them back within 10 minutes.

Telephone man" aint nothin wrong with my line, when I call these seller numbers, I get a deal every time." 

When cold calling what you're wanting are adults to answer the telephone and who "Want" to answer the telephone...So go get a newspaper and open it up to the classified section of Cars for Sale...
