Export my Maya 3d Rhino Model into Facerig so it works

Greetings! Lately I have found a person here to create a facerig model for me. Sadly the software itself wasn't familiar with the creator. He has prepared the model, rigged it and tried to put it into facerig, but facerig somehow doesn't see it. I need a person who can fix that! What I need from you is to turn my model into a facerig working character. The task shouldn't be hard as everything is prepared already.
