Looking for Design for Video Game Mockup?

Hi! I’m creating a short live action horror film that’s 9 minutes long, and it centers around a Twitch Streamer. During the film, we occasionally see the game he’s playing (from an over the shoulder perspective looking at the computer). It’s supposed to be an overwatch style game, and I’m looking to hire a freelancer who can basically help choreograph those sequences and record them so we can use them on the screen. I figured we would license a number of skins/characters and an environment from the marketplace and then build it from there.

It doesn’t need to be super complex, mainly just a first person shooting/battling some other characters in a town square style environment.

Let me know if you have any recs for something like this!!
