How much does a complex interactive animation in a prototype cost now?

Question

Layouts and prototypes

Began to master the creation of prototypes with interactive animation in the Pixate program. The service is new and it is not yet clear how to evaluate it. Share your thoughts with those who already have experience in upselling such a service to their customers.
UPD: the emphasis is on the prototypes of mobile applications, where the animation is just right. greatly affects the user experience.

Answer 1

Estimate how much you would like to receive per month for such work, divide this amount by the working hours and multiply the result by the hours that you actually spent on the prototype.
