Selling poker courses or whatever gambling related courses with a new account and no reputation known in this forum or in other platform is not a good start and as you are selling the courses is that there are courses that can be found online for free and even some app that are free to use where you can practice after learning the free poker courses that you have found. I think it will be hard to sell the poker courses you have as many people wanted to save money by learning from free poker courses.
I want to know the benefit of selling a course of poker to whom that don't know it so selling the course will it give any idea to someone who does not have the knowledge also someone who cannot make use of it so I think those things is a waste of time because even though you say it to somebody that does not know it it will be very difficult for someone to understand exactly what you are doing except it is facing that I have the basic knowledge of what you are selling to.
