Party Plan

You seem to be on the right track.
I don't have real experience with party plan selling, but I've sold to groups a few hundred times, from stage. So, there are similarities.

And I studied great speakers from the audience (and on DVDs), people that make huge fortunes selling on stage. I kept note of what triggered the best responses from the audience. I also studied terrible speakers, and speakers that were great on stage, but couldn't sell anything at the end. This last group may have been the most informative...studying failures, and trying to see the mistakes.

I also was always turned off by the tactics used to sell from the stage, selling to groups...even selling one on one.

But I found out that many of the things that completely turned me off, were really necessary to generate large volume in group sales.

For example;
Pretending that their lack of knowledge was someone else's fault, never their own.
Acting as though I was one of them, and saw the world as they did.
Pretending to identify with their "problems", and develop rapport that I never felt.
Praising audience members on the most banal of accomplishments.
pretending as though my expertise was just a matter of getting the right information (which of course I sold), and not a matter of years of hard work.
Showing emotion when telling stories that I told 1,000 times, just to trigger an emotional reaction.
Pretending like my offer was only good for a limited time, when anyone with a brain knew that was nonsense.

These are things I never liked. I felt like I was insulting the audience's intelligence. But I also knew...from costly experience...that these things were necessary, in order to make sales.

When speaking at events, even 3 day events, I had to wear a mask, act a part, never break character. It was exhausting. I got used to it, but I never enjoyed it.

My strong suspicion is that you would have to hold dozens of these parties yourself, to get the kinks out, and to recruit a core organization. But you will always have to be the person they expect you to be. There is no "letting your hair down", or relaxing your persona. If you do, even for a few minutes, it destroys their image of you, and they leave.

I've lost complete organizations by simply forgetting who they thought I was, and answered a question as myself. I can happen if you are tired.

One thing you'll absolutely need, is a Cause...a reason for your business to exist (other than to make money), All great sales companies have this. You have to be saving the buyers from some injustice, or solving a problem that they will see as important.

Simply selling lots of unrelated stuff because it makes lots of money, won't work. There has to be a Theme.
