3D photo realistic bag designs (x12)

I am looking for a skilled graphic designer who will be able to create 3D bags for our Parisian brand collection from drawings or sketches.
We are thinking of starting with a dozen designs. The designer must therefore be able to reproduce details with great precision, we seek a realistic effect that lets us question the design of the model, wondering whether it is a photo or a 3D.

The 3D models will be used to promote our collections on social media and our official website.

I would need to know :
- your price per bag design or your hourly price
- number of revisions per design

We promise more contracts if you manage to surprise us.

Sincerely,

Peter.
