Presentation / Speech Coach to improve my YouTube videos

Hello!

I'm looking for a PRESENTATION or SPEECH COACH that can help me improve my YouTube video presentation skills so that I can find my best genuine voice. I would like to video Skype or equivalent so we can practice and get it right. I expect we'd do a number of sessions to get it right. If this works I'm hoping to release a set of videos so I would expect I'd need more help over time.

I'm doing this because I have created a way to lose weight when you're not dieting, and I want to create a set of videos to build a community of people that follow the system. It's call the Life Hack "Diet".

For the videos I want to be able to show off my:
-Fun/Energetic side
-That I am professional
-That the content is relatable

I definitely don't want to appear
-Dull
-Like I know it all
-Over the top/over enthusiastic or forced!

A fine balance you might say! I want to work out what to do with my hands, and when to use gestures, and how to modulate my voice so I'm compelling when it needs to be!

I'd really like a few sessions on the phone/Skype so that we can chat through what I need to do to my current videos to make them better.

I'm including a link to my latest attempt, this is a practice and is uploaded as private:-

This is an example of a YouTuber that I like whom seems relatable and genuine:-

I look forward to working with you.

Cheers,
