Help with importing models into Gmod.

I have Searched and emailed a lot and nothing has worked. The furthest I get is an invisible object in g-mod. all of the tutorials out there are outdated and no longer work with current versions of Maya or g-mod. I would love for anyone who is currently doing this and has a work flow of some kind to tell me how they do this. I have followed the tutorials and read the wikis all of it is outdated and or I’m making small mistakes or don’t know the proper way.

 Anyone who is doing this currently I would love to know how. I'm an prop modeling and texture artiest and would be happy to repay any useful with a model of some kind if that helps any.
