Realistic VRM Avatar for Meetings

I want a VRM-format avatar (business male/female) that looks convincingly human. The brief is simple yet demanding: create a highly realistic digital double, complete with fine facial details, natural skin shading, hair that responds believably to light, and full-body rigging that keeps gestures smooth even on consumer-grade hardware.

The finished avatar must:
• Ship as a clean, single .vrm file ready for use in popular meeting pipelines such as Zoom via VTube Studio, Animaze or similar real-time software
• Include well-named blendshapes for visemes, eye-tracking, and nuanced facial expressions so lip-sync and reactions feel effortless
• Arrive fully textured (PBR), with materials optimized for realtime—target 60 fps on a mid-range GPU without sacrificing fidelity

Alongside the final model, please provide:
• Any native project files (Blender, Maya or equivalent) for future tweaks
• A brief setup note so my team can import the avatar and map tracking data within five minutes

Priority is photoreal excellence paired with corporate polish; everything should hold up under close scrutiny on a 1080p webcam feed. If you have past examples of similarly detailed VRM work, even better—share them so I can gauge style and performance.
