AI Avatar Voice Setup

I am a psychotherapist and author preparing short AI-generated videos that serve both marketing and educational roles around my book. I need a one-time configuration that lets me sit down afterward, open a browser, and record polished clips without outside help.

Here is what the setup must achieve
• A realistic, face-based avatar that looks formal and professional, not cartoon-styled
• A cloned voice that sounds clear and natural
• A workflow built in HeyGen or a comparable platform that I can reuse indefinitely

I can supply both high-quality photos and video recordings, as well as a clean audio sample for voice training. If additional material improves fidelity, just let me know up front.

Please outline in your proposal
1. The specific tool or service you recommend and why it suits this purpose
2. Exactly which files, angles, or recording lengths you require from me to build the avatar and voice
3. How you will hand over the system, including a concise walkthrough (recorded video or live call) that shows me how to log in, script, render, and download future videos myself

Deliverables
• Completed avatar file/profile inside the chosen platform
• Activated voice clone tied to that avatar
• One short demo video proving everything works
• Step-by-step guide or screen-share tutorial that I can replay whenever needed

I consider the job finished when I am able to log in solo, create a new clip, and publish a professional-looking video with my own likeness and voice in under ten minutes. Feel free to suggest any optional upgrades that fit this scope.
