Alyx Replacement

I was wondering if someone can complete an Alyx replacement model for use in Garry’s Mod that I found while looking for a non-FF Alyx replacement.
I found it in an .obj format. Sadly, I don’t know how this “rigging” and “UV mapping” works so I’m afraid I don’t know what to do with it so it would very kind if someone would please complete this?

Bump. Request is still open.
