Job: Looking for a Player Model to be created for games, such as Garry's Mod?

A bit back, I had an Avatar commissioned for the game "VRChat" and though the model looked really nice for the references that were provided, it turns out that porting that model into a game such as GMod would require a lot of work and remodeling, as a Blender Model doesn't work similarly to a FBX File, which from what I heard is better to upload Models for if it's finished.

So, I'm hoping that someone can recreate the model for me, as it's TECHNICALLY done, but I guess need to be remade in order to work for Garry's Mod, and possibly other games.

Hopefully I can find someone to assist with this!
