Music Teacher Client Portal Student Login

G’day

I am a guitar teacher running the following site https://www.theflamencogypsy.com/

I currently teach lessons online using skype, and would like to create a client portal for students to logon to. I would like this page (I guess it doesn’t need to be a page) unique to every student. I would like them to have access to all of my regular resources plus the extra ones for them alone. I attempted a client portal with s2member but currently they have an issue with linking the student to their login welcome page.
That being said I don’t quite understand how I would even create a unique client login/portal if it did work properly. I would like them to have access to video’s and PDF’s and so forth, but I definitely want a student area behind a login.

If anyone has any ideas on how I could create this I would be very grateful.
