Create specific texture of stone wall

Hi all,

I premise that we do not use substance in our workflow and I hope this post is aligned with community rules.
If anyone is able to create the attached texture, please email us at [removed by moderator] specifying the asking price for creating a seamless texture (with associated normals, roughness, displacement, ao..)

The texture we need to use it for wall wall covering, so we would need at least 6-8k resolution and approximate size of at least 3x3 mt.

Thanks to all
