Professional video making for a series of 20 faceless videos for YouTube

I need a professional video maker to work on 20 faceless videos designed for YouTube. The videos are intended to help non-English speakers to start their way into the language. Including but not only: 1) stock footage, images, animations, transitions, video effects, audio and videos excerpts (respecting legal use); 2) Human narration 3) creation of video quizzes 4) thumbnails for each video 5) Subtitles in English and Brazilian Portuguese. I'll provide the 20 scripts generated by A.I. and revised by me. The average length of each video is of 10 minutes. Example of a script and directions on what to have on-screen or develop the video activities: [SCREEN: Intro animation with logo and upbeat background music] [NARRATION] "Hello, superstars!
