This is ambitious Dave. And not to be insensitive, this is a lot to take on at this stage of life. 

Have you thought of talking to a good teacher who can review where you are at, what you see yourself doing, and what is realistically achievable?

This site has tons of resources, you just need direction on what to do. I don’t know if Christopher gives lessons but you should definitely reach out to him. He has his own forum.
