Course Implementation

Does UNA have starter or at least running sample Course CMS that allow instructor/coach to SELL their own courses. To be able approach that case, do we need to separate Instructor and Person Profile? what is the best way to achieve this?

A. By permission > how to allow Create Account and set specific permissions? from the Default profile type I can set this for the normal user (student) as "Person" but how we can create an Instructor registration and give them profile type as "Instructor"?

B. Custom module derived from Person module?
