Enabling VR to our Game (NEWB HELP)

I have Unity Pro 5.1

I am a graphic guy, but my software needs VR support. The guy that did the main core of coding/input to creating our game can’t work on it for a month but we need to VR ASAP so am going to try to do it myself. I have access to all the files (Google Drive).

Here is our game,

http://virtualcoachfootball.com/vc3dplayer/

Username: demo
Password: demo

So I am looking for a step by step easiest newb guide to enabling a VR Mode in the game part. Where the play/pause button is I would like a [VR] button that sets the view down of the field and lets users use their Oculus Rifts.

Thanks for all the help in my quest into turning this VR.

Ok, so I added the Prefab OVRPlayerController to the Hierarchy.

But when I play the game, the camera falls through the floor and continues down.

Any help is extremely appreciated!
