Dan,
My initial thought is that you are not providing enough "need development and satisfaction" to merit getting the business.
I would start by asking some of the advisors that you or your partner have closed why they decided to purchase the membership and what they have been able to get out of it. Get them to tell you a success story. Then, when you can get a prospect on the phone, you can have a conversation that develops need through a story.
For example,
Hello Bob. I'm Dan with ___________. We provide financial advisors with a capability to develop business exit strategies for their clients.
For example, I was talking with an advisor the other day who needed to [state the problem you solve] for his client. He said that if he could provide an exit strategy for his client, he could [state the direct financial benefit to the advisor – additional fees, new business, etc.] while he provided his client with an exit strategy that [state the direct benefit of the exit strategy for the advisor's client – tax financial benefits, etc.].
I was able to show him a solution that provided those capabilities.
As a result, this advisor was able to generate [state the dollar benefit your solution delivered – new business, additional fees from current clients, etc.].
But enough about me. Tell me a little about you. Are any of your clients looking to you to help them develop exit strategies for their businesses?
Build on a few more qualification questions and some brief statements explaining what the exact service you provide looks like. The goal is to develop data about what this kind of capability could deliver to the advisor. Then ask for the order:
"So, based on what I'm hearing, you think you could generate $X,XXX by being able to more effectively develop business exit strategies for your clients. How about if you tried this service risk-free for one month. If it doesn't deliver the benefit you think it can, then you can call me up and cancel with no further obligation and we'll part friends. Can I get you started?"
Then SHUT UP. The next person to talk loses.
You are either going to get an order or get objections. Have non-defensive answers to every objection they can throw at you and circle back around to your closing statement.
These are my initial thoughts. I'll 'noodle' on it a little more and see if anything else pops into my head.
