I'll be happy to make you an app where different events can be seen on the timeline as illustrated by you in the video in drive.
Honestly speaking, I like the idea of yours to put the events on timeline, it'll help people understand of occurrences of historical events better.
The text, images, videos can be uploaded at once to correct timeline from CSV file.
It'll include all the listed features by you.
I’ll make sure that your app will look elegant in all major devices, it’ll be faster and light-weighted (saving server costs), it’ll be robust to withstand cyber attacks and scalable as you grow your business.
You pay at the very end when you are happy with the work.
