URGENT: I need a custom avatar by 20th November but don't have a real person to record a 2 min video.

I have an event after 20th Nov where I need to showcase a custom avatar chat bot.
I am not allowed to use a real person avatar for this.
Is it possible to use a realistic 2 min video of a person generated by AI? I don't care if the quality of the avatar is not great, I just need a good enough custom avatar that works.
Please help me. I have already paid for the custom avatar.
