How to organize the sale of an info course?

Question

Business Informatics

One friend was confused to sell his knowledge.
He is an expert in a certain area.
This specialist created a good product for sale in the form of an info course (materials, video presentations, presentations, articles, plans for speeches and training were prepared, a quality program was compiled).
It is planned to provide the product in the form of webinars.
What is the best and most profitable way to sell this course?
There are two questions:
- personally
- through intermediaries (schools, etc. online).
If a specialist wants to sell the course himself, what should he do?
I suspect the beginning is this: he orders a website, or even a simple landing page, and promotes it.
How to implement a mechanism for registering users, paying for a course, enrolling in a course, tracking all this.
Couldn't it be that if he gives the landing page to the development of the programmer, he does it, and for the "pay" button he assigns his data.
Those who wish to participate in the course pay for the classes and the money goes to the programmer. How can this be avoided and controlled so that it does not happen?
Are there ready-made paid and free similar systems for organizing such events, including so that you can attach your own design there,
connect payment details, and so on?
If a specialist wants to sell a course through intermediaries, what offices would you recommend? What to look out for and avoid being scammed?
Who has already organized the sale of such things and their competencies in certain areas, the specialist who asked to ask this question here will be happy to talk with you.
You can leave your contact details, he will contact you to communicate with you.

Answer 1

1) Create a free course that describes the problem briefly, 5-7 lessons.
2) Create an account on www.getresponse.ru and create a subscription form in the constructor (if you can't do it yourself).
3) Drive all traffic to the subscription form, users receive your mini-course and leave their email.
4) Create a one-pager linked to a robokassa or a service like e-autopay.com for your main course.
5) Set up a series of letters in the getrespons service so that all users who have passed your mini-course receive a letter with the main course offer and a link to the salesperson.
6) Profit..
