is there any webcam platform with good offers for studios?

I have a number of models I work with and for a long time I have been looking for a place where they can perform on webcam.

Most sites I have found are only interested in the models and pay nothing to the studios. Others pay something to the studio at the beginning and then they forget. Also these sites have too strict rules, not allowing models for example to promote their own porn movies.

If I am bringing my models I want to earn a lifetime commission on the work they do. And I want that my modes are allowed to promote their contents by redirecting users to the website where they can buy movies with this model. Do you people know about some cam platform that allows all these things? I have been searching for a long time with no success.
