The most easy way would be to go to Zarniwoop's character dungeon and solve the puzzles, you need to do that every time you want it though.

The (far) more complicated approach is to get the public model Disaccord Noob provided, import the .fbx into blender, figure out how to make it work by either yourself (a pain) or geting it to work with the Cats plug-in (little less pain, but still the hardest part), export it back into a .fbx, import it to Unity, assign the correct Bones and assign and tweak Dynamic Bones which you need to buy.
All to find out those three vertices weren't weighted properly and do it all again.

As VRChat currently is, there's no real way to share Avatars besides pedestals, sorry.

If you send me a friend request I could maybe help you, but it might take me some time (a few days at least) to get back to it.
