Who is a non-beginner? Someone who is comfortable with his instrument. Ukulele players , often self-taught or have taken a few beginner workshops, are non-beginners if they already know how to tune, play the basic chords from memory (C, F, G7, Am, C7) and strum instinctively. They know how to read a chord diagram. They know how to look at a song sheet and finger the chords indicated with the lyrics.
What would a “ukulele for the non-beginner / busy adult” course include?
