Facebook marketing for high-ticket coaching packages and business consulting

I am reaching out to you from our company, Earth Pulse Academy, we do high-ticket group coaching packages with a custom built 4 month long spiritual program(~5000$) that has been rated as the best in the world by our past clients. We also allow our clients to follow up our coaching package with an extensive 4 month facilitator training(~5000$) and/or an extensive 4 month program on how to build your coaching business(~5000$). All packages and combinations of packages also have payment plans available. Generally we've got our business down, but we are really struggling with facebook marketing. Currently we have a facebook ad campaign that moves people into a marketing funnel which you can find here: [login to view URL] We have tried different targeting strategies, and different content in our funnel, but the problems we run into are generally, either we get people on sales calls who cannot afford our program or have to check with their partner and then we never hear from them again, or we get extremely low registrations for our webinar inside of our funnel and 0 calls booked. What we need is to get people from our ad through the funnel into a call who feel excited about getting one or more of our programs and are able to pay for them either outright or in the form of a (4-12month) payment plan. If you're willing to take a deep dive with us into what we already have set up, and figure something out that works for us, please let us know, and if necessary we can also give you more detailed insights into our payment plan models, and past marketing performance with different setups.
