Need my website made for coaches and gym goers, making plans, educational videos and specific tailored programmes

I made a start to a website, I want it to have multiple options. it has standard programmes that i make for someone who goes gym. Multiple possibly a questionnaire to unlock certain programmes that would best suit the customer. Let them make a one time purchase for a programme or unlock all with a membership they pay monthly. For these programmes i want a video showing how to do the form correctly that coaches can add to demonstrating how! I want sections for each exercise saying tempo, sets, reps, weight and have it to say type of exercise for example 'superset' and more. I want a section where i can add educational videos explaining nutrition and other factors in fitness that would be tied in with the membership maybe have it as another membership option and also have each video as a certain price but membership unlocks all videos. Then for most important part allowing different coaches with this website to amend clients programmes and charge clients for specifically tailored programmes but i get 10% of the income they receive from each programme and they will get paid from the website and have their earning in a separate tab. I want their programmes they design to be on the website fully customizable and also viewable after they prescribe it to a client to track progress.
