Creating 3D models for games (multi-platform)

I'm building a space strategy in Unity3D.
I am looking for a designer who can create 3D models of ships, bases, asteroids. (Animation)
I can't pay for your job right away. When the game comes out, when it starts to make money, I'll buy your models at your price. And it is possible to find employment on a permanent basis.
If you are thinking about taking up or not taking up the project, I recommend taking up the project. At the very least, you will increase your portfolio.
