CAD designs and 3D rendering for Shopify Website

I am looking for someone to help with CAD designs/realistic 3D renderings for an engagement ring catalogue that will be displayed on a Shopify website.

I have attached two rings as examples.

How much would it cost for you to develop CAD images and 3 renders for each style?

If we wanted to get the same rings in another stone shape e.g. princess cut, what would be the additional cost?

If we wanted to get the same ring but in another colour e.g. white gold, what would be the additional cost?

Hope to hear from you.

Kind regards,

Ayo
