How much and how do you charge for a 15 hours advance excel tutorial

Hello I was wondering how much can I charge to create an advance excel tutorial that last 15 hours that has video lessons (demos), assessments (simulations), and multiple choice. Can I charge one time, if so how much? Or can I create a license that I charge for the creation of the content and a monthly fee to use the tutorial.

Splinting a slide in the simulation

Hello I am using adobe captivate 9 and need to slip a simulation slide so I can delete the part that I don’t want. If there is no such feature in Adobe Captivate 9, is there a version that has it?
