Education theme setup

Hi, I’ve been testing different themes and plugins for 2 weeks now but I can’t find a good solution. Can anyone give me a tip? The case are:

I have a education course that companies can buy from me. I want to give every company two login to my wordpress site. One for the people that are taking the course, the course are videos, texts and som quizz. And one for the corporate manager that will se results from the quiss and how many that has taken it.

I’ve tried with complex education themes, but they are very hard to adjust and complex to setup. Feels that it’s to much for my needs.

What I need are som kind of group or area that each company can log in to and that I can Customize for the company and where they can see different education posts. Ideas?? KR Andreas
