I've been consistently satisfied with my researching skills. It's nice that you've collected a lot of stuff, but I don't really need you to do that for me. What I need is someone that understands why I personally have problems making presentations and what I can do to fix them. Then I need her to coach me or review my videos.

(Hypothetical customer me, that is. Real me just got home from teaching.)

You should address how you intend to teach people to present, or otherwise display that you have some understanding of where their problems are. I also second the notion that you are going to want a video in your promotional materials.
