VR coaching

I am looking for someone who can build an environment for me in VR that incorporates interactions. Could be Unity or Unreal. I have a vision of building various environments that evoke certain types of emotions and in some of these environments, for there be some interactions e.g. a room where you need to build a tower but its an impossible task and I would observe their reaction. another room that is a cavern for example and has danger signs, do they still open the box that says danger on it? another room that has a puzzle to solve, another room where you need to find clues in order to leave the room, an auditorium where you need to present something etc. // Hopefully that paints a bit of a picture of what I am looking for. At this stage, I would like to understand what's possible, how much it would cost, timeframe and where it would be hosted. I work in VR creating learning experiences so I am familiar with the technology and what's possible but I am not a coder so can't build the environments myself. I am a coach and want to be able to offer something different for my clients, to help them in their careers and self-belief. Thanks :) Lucie
