3D Robot Dog Character Neural Bot (3D modelling)

We would like to design a 3D dog robot from scratch or have someone work from another purchased dog robot design, whichever is most efficient and cost effective. We want the 3D dog robot to be anatomically like a dog and joints and movement that will mimic any dogs movement.

So, that would mean having as many joints, limbs, hips, back, neck, and as much rigged as possible for animation. We purchased this dog and would like our 3D robot dog rigged and to be able to be animated like this https://sketchfab.com/3d-models/dog-border-collie-dd510251c1a84b01be82a17341a51ebc

We already have a pack of real dog models we’ve purchased that are already rigged and imported to Blender, and we can provide those as base models to edit as needed and base the 3D model. We expect a few iterations of back-and-forth to get the joints right (add, reposition, etc).

Here's a few links to inspiration files and what we're looking for. We like the white style more so than the robotic/gear like look of some of the files.

We are looking for a fixed project cost.
