Help with best camera & setup

[ianmoone332000]

So i have a friend whos looking for advice:

"Thinking of setting up a 3 camera studio, with mixer. Want for shooting content and advanced camming so the girls can see each cam on a large monitor and select which cam to stream"

Iv got him to sign up here so just waiting on approval. Just looking for ideas on what would be the best way to do this and also the best equipment etc

3 Blackmagic Pocket 4k cameras and 1 Blackmagic ATEM Mini Pro. If you've got a laptop and an internet connection...you can do a heck of a lot with this setup.
