Futuristic 3D Robotic Horse Adaptation

I'm looking for a skilled 3D modeler with extensive experience in Blender to transform an existing 3D horse model into a futuristic robotic version. The model must be fully compatible with Unity and delivered in .fbx format, complete with modified textures.

Key Requirements:

Dynamic Color Change: Implement dynamic color change capabilities using material property adjustments within Unity.
Texture Variations: Create multiple texture variations (e.g., metallic, matte) for the model.
Robotic Features: Ensure the model incorporates essential features to achieve a robotic aesthetic.
Animation Rigging: Maintain compatibility of the existing animation rigging with the modified model.
What I Will Provide:

A base FBX file and textures that need to be modified.
Ideal Freelancer:

Portfolio: A strong portfolio showcasing previous work with robotic and futuristic models.
Blender Expertise: Extensive experience in Blender, particularly in adapting pre-existing models.
Unity Knowledge: A solid understanding of Unity and its compatibility requirements.
Interactive Features: Ability to create and implement dynamic, interactive features within a model.
The final deliverable must be fully compatible with Unity and retain all necessary features for proper functionality within the engine.
