AI Video Creator Needed — Realistic AI-Generated Videos at Scale

I'm looking for an experienced AI video creator to help me build a system for producing realistic, high-quality AI-generated videos at scale.

I have a reference account showcasing the exact style of video I'm aiming for, which I'll share during our first conversation.

What I need:

Help defining and setting up a repeatable workflow/system to produce this type of video consistently
Consistent visual style and color grading across all videos (same look and feel every time)
Recurring characters/people that stay visually consistent from video to video (same "face"/persona across the series)
Ongoing production of videos in bulk once the process is validated
A clear breakdown of the tools/software involved and the estimated cost per video (production budget)

Before we start working together:
Please share examples of similar realistic AI-generated videos you've created, ideally with consistent characters and style across multiple videos, or be ready to produce a short test/sample so I can confirm you're able to deliver the quality, consistency, and character continuity I'm looking for. This is a required step before any contract is signed.

Ideal candidate:

Proven experience with AI video generation tools (e.g., Runway, HeyGen, Sora, Kling, ElevenLabs, or similar)
Experience maintaining character/persona consistency across multiple AI-generated videos
Understanding of what makes AI video look realistic (motion, voice, lip-sync, lighting, color grading)
Able to document and explain the workflow so it can be scaled/replicated
Comfortable working iteratively and giving cost estimates upfront

Please apply with relevant samples (bonus if they show the same character across several videos) and your estimated cost per video for a typical production.
