Expert Screen Narrator and Idea Creator

I am looking for an expert who will be creating unique ideas and have access to my computer to task record while narrating, typing on recordings screen. you must be expert in ideas creating and know English to narrate it what you are typing, where you’re clicking and why it’s deliverable. You must use three apps like words, excel, power points. Each task recorded must be between 15 - 40 minutes. No video of yourself, just the narrative voice. No access to outside tabs on the screen when recording, just only the artifact apps within the task record, no screen overlapping. I can generate ideas which you’d be comfortable to narrate and expert on it. It could be you are designing something. Something complex and depths, not easy for anyone to copy and paste
