Blender Models to Source Engine

Hello, I’m trying to guide a student so he can send his Blender models to the Source Game engine for use in a game called Gmod. I’m following the directions here: https://steamcommunity.com/sharedfiles/filedetails/?id=702924242

I get everything up until the section on “Setting up the QC.” Any help is much appreciated. Is anyone here familiar with exporting blender models to the Source engine? Please provide any resources you can. Thanks!
