I have experience in online pricing models, but it would be impossible to provide price points that would be anything other than a guess with the information given in the OP.
- How many interactive quizzes? What will the frequency of new quizzes be?
- How often will online articles be posted? What will the ratio of amateur to professional be?
- How many instructional videos? How often will new videos be published?
- How many health, wellness, and workout tips? Will these be written by a trained medical professional?
- Define "considerable" as is pertains to umpire school discounts?
