Unity simulator software

I am looking for a Unity programmer to help me create a driving simulator software for offline use. This software will have interactive 3D elements incorporated into it, but I’m not sure about how sophisticated and detailed they should be. The main purpose of this software is to give users a virtual experience of driving and navigating a vehicle on a course in-game. The programmer should be creative and able to provide realistic simulations unlike any other. The game should also be able to run well on PCs with minimum hardware requirements. The programmer should be proficient in Unity and be able to deliver a fully functioning software in a timely manner.
