Automated Devotional Video Pipeline + Multi-Platform Upload + Character-Consistent ComfyUI Workflow

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 1 — Automatic Multi-Platform Upload System
Goal: Fully automate upload of generated videos to:
Facebook
Multiple Instagram accounts
TikTok
WhatsApp Business
LinkedIn
Threads
YouTube

Requirements:
Accepts video files from an existing local workflow (folder or webhook input).
API-based upload, reliable, with proper handling of metadata (caption, tags, cover image).
If possible: Scheduling option (e.g., “post daily at 09:00”).
Must run locally or via a lightweight script (Python preferred).
Payment:
200 € if everything runs without me needing to be involved for more than 1 hour
100 € if a lot of troubleshooting is required and I must assist for more than an hour

Stop condition: If it takes more than 5 hours of my own involvement testing/troubleshooting, I will end the project.
