Looking for help with optimizing VRChat Model for Quest

Hello! I have been struggling to optimize a model I commissioned. It is fully rigged and everything, but it has too many polygons and gives me several non-autofix issues that I can’t find solutions for. I need it to be Quest compatible because I play on a Quest 2. If someone is willing to help me make the model Quest compatible, I would seriously appreciate it.

You have creators in Avatar Commissions that could help you, else maybe check out websites like fiver and such.
