Time to create the course in Stan Store. (or which ever software you choose)
This will allow you to start promoting the course and start making money!
Keep this really simple,
You don't need to have all the "backend" stuff figured out yet.
Just create the shell of the course.
Make sure you tell people this is pre-sale and that they get to build the course out with you.
And tell people that is why they are getting a discount on the course.
Once you get that completed, post the link to your course below so we can check it out!
