Course for Women in Tech Suffering Imposter Syndrome

So I bought this domain about a month ago in a flurry of inspiration
www.impostersyndromegone.com

I have been a software engineer in corporate America for 4+ years and boy have I suffered an excruciating amount of imposter syndrome. I also have a pretty expansive knowledge of psychology from dealing with panic, anxiety, and trauma. I touched on these issues in my book "Foot in the Door" but I realized that I could write a loooot more about the topic. From sharing personal experiences to therapeutic exercises to identifying toxic workplaces, I think there is a lot of information I could share.

Sooo I was thinking I could create a course, and possibly a support group as well. Obviously I could expand the course for more than just women in tech, but I think being a woman in tech myself I have the most to offer that audience and I can always expand it later if it is successful.

Anyway I was curious about what people here think about this idea, and also whether or not it would be a good idea to first create a landing page with some introductory material and a signup form so that I gauge the level of interest before pouring tons of work into this. I was also thinking to maybe do a raffle or something for the first 10-50 people who sign up to have free access to the course so I can do some polish and improvement before charging people because frankly I'm a bit terrified of having an angry mob demanding their money back.
