[I need some advice on how to price my game testing gig.]

I have a YouTube channel here: https://www.youtube.com/@goony1249/videos

On this channel I play peoples games, give feedback and find bugs in them. 

I'm just unsure how I would price this because I test their whole game and can do multiple videos.

I was thinking maybe I price it based on how many videos or maybe I just sell the feedback in itself.

I'll post an example here.
