3D Character Artist — Realistic Female Avatar with Facial Rigging & Viseme Blend Shapes (GLB/glTF)

Description:
I'm building a voice AI English tutoring app and need a high-quality, real-time 3D female character created from a photo reference. The character will be displayed in a web browser (Three.js/WebGL) and must animate in real-time with lip sync driven by audio.
The character:

Warm, friendly American woman, approximately 25 years old
Based on a provided reference photo (auburn/brown hair, blue eyes, professional appearance)
Must feel approachable and trustworthy — this is a tutor, not a game character

Technical requirements:

Game-ready / real-time optimized (under 50k polygons)
GLB/glTF format
Full viseme blend shape set minimum 15 shapes: sil, PP, FF, TH, DD, kk, CH, SS, nn, RR, aa, E, I, O, U
Additional blend shapes: blink, brow raise, smile, neutral
Compatible with Three.js / React Three Fiber
Rigged for subtle idle animation (head movement, blinking)
Clean UV mapping, PBR textures

Deliverables:

Final .glb file
Texture maps (albedo, normal, roughness)
Short demo video showing lip sync in action

Budget: $300–$600 depending on quality
IMPORTANT — I require a paid test before full commission:
Before awarding the full project I will pay $50 for a test deliverable: take the reference photo I provide and deliver a head mesh in GLB format with 5 working viseme blend shapes (neutral, jaw open, smile, O shape, F shape). This protects both of us and ensures we're aligned before the full project begins.
Do not apply if:

You cannot demonstrate working viseme blend shapes
You don't know what Three.js or real-time rendering means
Your portfolio only shows cinematic or stylized characters

To apply, please include:

Link to your portfolio showing realistic human characters
Examples of facial rigging or blend shape work specifically
Confirmation that you understand the viseme requirement
Your estimated timeline

I am ready to start the test commission immediately upon finding the right artist.
