Hi there!
I would be happy to write an excellent script for your video. I've worked as a professional writer, screenwriter and editor for more than 20 years. During that time, I've done my fair share of writing for videos, including industrial, short "explainer" videos as you describe, longer educational videos and more.
As a former teacher, I always make sure whatever I'm writing makes sense to the viewer, reader and will be absorbed readily.
I"m great with deadlines, and a video of this short length would be simple to knock out in a day, even with going back & forth with you for any necessary revisions, edits, etc.
I look forward to hearing from you, and thank you for your time & consideration.
Best,
Cheryl E. Booth
