Help screen recording some training videos

We have an accountancy training portal where there are videos added each month, we want to download these and do this in such a way that we can:-

-Create a transcript of the content of the video
-Add chapters for key areas
-Produce a summary of key points
(any thoughts on this would be helpful)

The purpose of this is to make the content more accessible for us, so that we don't have to watch the entire video, we can just watch key parts, then also if there is a summary and transcript we can add this to a searchable database where we can search for specific terms and find the relevant content.

I've made a video of the portal, unfortunately it is not possible to download the videos, so I think the only way is to use a screen capture and record the full video. Most videos are 1 hour in length.

I'm not sure on the price, I guess that depends on the number of videos we download. We wouldn't want to download them all, maybe just 5 per month or so. But at the start we'll download quite a lot more of course.

Here is the overview

I have set the budget based on recording 10 videos of 1 hour each in length. Let me know if you want to charge a different price, this is just an estimate.
