Grand Theft Auto Custom Players (Mostly from Final Fantasy) to Garry's Mod; Model Porting

[Brief]

Original Thread: [url]http://www.facepunch.com/threads/1049115-Grand-Theft-Auto-to-Garry-s-Mod-Model-Porting?highlight=[/url] (I didn't want to confuse people, so I made a new thread.)

I was wondering if it was possible to port models customly rigged for Grand Theft Auto into ones for gmod; like player models, ragdolls, etc.
If someone knows how to do this, I'd really appreciate it.
I'm willing to pay, so here are a few models I'd like ported.
