Question Bank Website Developer

I'm looking to build a question bank website for medical students to answer practice questions.

The website should have:

- Home page for users to sign up / sign up
- Home page once signed up showing you topics of questions so you can select
- The questions, once you answer a question you can see the answer and explanation (and potentially so embedded YouTube videos for answers)
- A way to take payments for people buying subscription
- A contact page
- A page for the admin (me) to upload new questions and for users to submit questions


Notes
- Questions should have flairs / categories to aid for sorting
- A few other features to be discussed privately with chosen application
- I would like to consider if we could add AI into this project somehow

Here is an example of a similar website:
