Photo Realistic Product CGI's of Unisex card wallets

We are in the process of designing a new range of RFID wallets.
Attached are the sketched designs and supporting technical specification guide for each style. There are 2 styles.
We require each design to be made into photorealistic CGIs on a white or black background to enable them to look premium . Replicating the angles of the sketches would suffice.
We would also need to show each design style in the alternative colour options shown in the technical guides
The two designs that need developing into CGIs are enclosed in the Zip files labelled Anna and Rebecca.
I've also enclosed the logo files for the brand element.
Here's an example competitor product for comparison: https://bellroy.com/products/slim-sleeve-wallet/default/caramel#image-2

Could you provide an estimate for delivering the images please along with examples of your work.
It is important that these images look as realistic as possible so attention to detail is critical
