Probably every dialer company has lists they can sell you.I think it is better to call yourself vs using cold callers. 

If so, how many, how long, and what are the covenants for qualifying for the extensions?

Try being an agent, your phone number is EVERYWHERE and you get targeted by a whole industry that wants to sell you the latest gimmick.Here is what helped me.I answer calls and when it's a telemarketer I will interrupt them and say very friendly (because I don't hate the poor person who gets paid to do this and coached to be ruthless): Hey, so glad you called, can you do me a big favor? 

Plus we had the money to pay one off if it got called and we did have a few get called ..

So I decided to sell and move on. 

All this turkey does is charge you for some "training," so you will be "prepared" when you go out looking for lots for him, but curiously, he buys none or very few of the lots he's sent.  

They haven't emailed or called me back yet.I just also called Doug Michie in Ventura but got an answering machine so I left voice mail asking him about this as well.Hopefully, they will contact me next week.

I rarely get any calls and never got any of these top 10.

One of their so called instructors from one of the training sessions asks the students to go to the five star hotels, or go play golf, or go horse riding, or go hang out at the high end night clubs for the sake of fund raising.

The seller is representing themselves so showings must be arranged with them, and offers made to them directly.
