Will Squarespace work for me?

Wondering if SP will work for me.  Lets say I am a school.  We need to have a main page for the school but we will have many teachers using our platform to teach their own unique curriculums.  Their lessons will be in video and there need to be video storage capability as well for archived lessons.  Each teachers page will be under our main page but their content needs to be private.  Does that make sense?  We will not be charging a subscription but teachers will pay us annually for having their own cyber classrooms.

Well first thing is that Squarespace does not store video. That would need to be hosted with vimeo or you tube for that. You can link the videos to the site and they would play in a site window or full screen. You can password pages to keep them private, and have multiple contributors. The pay part would be outside the scope of the site.
