Teen Mental Health Live-Action Teaching Video

I have created a mental health course which i wat to sell to private schools / academies. I want an actor to film the first two lessons to give my clients a look in to what the course will look like when its taught. Ideally i want a young man or young woman that has a quintessentially English accent and has a real passion for conveying his or her communication skills. The actor will be working from a script but will also be pretending that a teen audience is Infront of her so as to give the impression that its being filmed in front of a live classroom.
