What kind of team am I looking at to develop a VR game?

Hey there. I’m completely new to this so I apologize if I ask some really stupid questions.

I’m looking to create a small VR game that utilizes Leap Motion Sensors (or something equivalent for less hardware). I did some research and it’s similar concept to what The Void has done with an overlay on physical structures. It’ll have a few levels, checkpoints and endings. Multiple players (4-5) that are able to interact and see each other within the game. The whole game should only last 45-60min.

How many people do I need to have in this team? If there are any details that I am missing, please let me know and I’ll edit this post.

Thank you!
