Devotional Video Automation Enhancement

Summary
I am looking for an experienced developer (AI, automation, ComfyUI) to finalize and professionalize my current devotional video automation system. I already have a functioning local n8n workflow that generates devotional videos via local comfyui wan2.2 (text + audio + 10 image prompts), but now I need three major upgrades:
TASK 3 — Character-Consistent ComfyUI Workflow (3–10 characters)

Goal: Build a 3-minute video creation pipeline with consistent characters — similar to Wan2.2 output quality.

Functional Requirements
Characters should be reusable across projects.
Each character gets a persistent ID: face, eyes, skin tone, outfit, style.
Workflow should accept a story prompt and generate image/video sequences automatically.

Optional but ideal: A system for creating characters once and storing them for future videos.

Payment Depending on Solution
best: Full system for reusable characters with persistent IDs
bonus: If the workflow can generate entire stories (3 minutes) with character-consistent high-quality video (Wan 2.2-like)
not enough: If the solution is only a basic image-reference workflow, I can do that myself

General Requirements
Good communication
Experience with: ComfyUI, Python, automation, APIs, LLM agents, local models
Must work 100% on Windows 11 local comfyui
