LMS for WP

Hello,

My problem is this: The client want LMS solution for Word Press but its not like the Moodle. Can you please help me and give me some good solution for this. This is some of of the necessary things what need for the system:

1.) Login and register for students.
2.) Option lesson for students and public lesson
3.) Each student sees only their lesson when login, but also can see the public lessons
4.) Need to support video embed
5.) Option for purchase the lessons
6.) This is not important but if can have the ” send the massage to teacher ” will be plus.
7.) Also option for courses ( I think this is same like lesson )

Thank you very much for help…
