Thanks.
Ouch, I was grossly underestimating (the cost). It would mean on the range of 1500 USD for each video, and from what someone else indicated as his montly income from Patreon, it would mean around 720k budget for him for a full video.
I am certainly not minimising his skills (as I said, I like his work), which are certainly without comparison with mine (can do video editing, never even tried animation), and I admit it is somehow bad mannered and wrong to "make calculations in someone else's pocket" (if you allow the expression) but I am sure there is a decent number of "indie" film makers that would have to do with less budget for a movie with real actors.
