I need a 3d model from an image, textured, and fully rigged in Blender, ready to be used as a unity asset.

I want something like this robot, rigged for basic movement such that it can be used in unity as a character, It will be URP, no facial movements, 'hands' are 3 fingers that close and open as a robot claw, so no finger articulation required other than that.

I would like a blender model so I can tweak it myself as required in the future. with either a unity asset or demonstration/instructions for making it work in unity.

There will be multiple of these in frame (think lemmings!) so needs to be a sensible poly count.
