Hi,
Your project sounds very interesting and I believe that I'll be able to perform the task perfectly.
I have over 15 years of experience as Physics and Math teacher; but, I've also done some VA work, which included a lot of both Excel and MS Word work (Templates, Macros and complex formulas, conditional formatting, etc). My wife is a writer and she helped me with some video-tutorials, including script, video editing and voice-over. In my portfolio you can find a sample of one video-tutorial for a website. The video is created in Camtasia. https://www.freelancer.com/u/milanmartinjuk.html
If you choose me for this project please contact me before "awarding", because I would like to hear more about this project and modify my price after we agree on details.
You're welcome to check my reviews and should you have any questions, I'll be happy to answer.
Kindest regards.
Milan
