Hey Gen Clone user needs help in doing a LIVE Avatar Clone for 24/7 Coaching site

I see you offer 30 day trial for me bc I have clones in HeyGen. How do I get started building a live interactive Avatar? With Migration of what I alredy have in Hey Gen? I am not a Tecky, so I need easy step-by-step on HOW and WHERE to create this new LIVE Avatar if I need to start from scratch. DO you have Demo Videos to help us? I want people to pay, chosing from 3 tiers of programs (and time to chat) what type of Avatar mode do I choose - Full or Custom? WHERE do we upload our content to train it - I have aiCoaches Custom Bot already, can their API code go somewhere so I don't have to start content from scratch?
