What could be the price for animated 3D models, for the smartphone application?

Hello!
I really need an advice.

What could be the price for the creation of animated 3D models, for the smartphone application that uses them with augmented reality?
As I understand it, the system requirements for smartphones and tablets require low-poly models with simple facial expressions.

That varies so much. How much animation is needed is a big factor. How detailed the model is is another factor. A rough estimate is $200-$2000 per model.
