Modern 3D Cartoon Character Modeling

I am building a YouTube kids animation web series (ages 3–7) and need a stylized cartoon 3D character modeled and fully rigged in Blender.
The first character is a playful stylized kitten (non-realistic, soft shapes, big expressive eyes).
This is NOT a realistic or game-style character.
Requirements:
Stylized modern cartoon style (soft, rounded shapes)
Clean quad topology (animation-friendly)
Full body rig
Facial rig (eyes, brows, mouth controls)
Tail spline rig (important for expressions)
Blender (.blend) file required
FBX export required
Commercial rights included
The character must be suitable for an animated web series (recurring episodes).
Please include:
Stylized character examples
Wireframe screenshot
Short rig demo video
Budget range: €700–€1,200 depending on experience and quality.

This is the first character of a potential recurring series project.

These are reference images for style direction.
The 2D version is the original brand design.
The 3D render is the style direction I want (soft stylized modern cartoon, not realistic, not game-style).
The final result should stay true to the original character but be animation-ready and fully rigged.
