Film an online course

We are creating an online course and need a person who can be "the face" of the course. Course will be about aviation and will consist of around 12 videos. Scripts and texts will be provided by us. You will have to film 12 videos explaining theory (that will be provided to you) and send the final videos to us. I am looking for a person who has: 1) Perfect spoken English; 2) Good appearance and style; 3) Has been filmed before and can shove some videos of him; 4) All genders can apply; 5) Really good camera. Please add your previous work to an application for prove. Good luck!
