Sorry about the "two bottom lines". But hey, you have to take what you get when it's early in the morning and I've just waken up - like right now for example.
Don't give up your dreams. You've got exactly twice the total flight time that I had when I was 28. I wish that I could offer you some meaningful advice, but I have little (read: no) understanding of how one breaks into the game on your side of the Atlantic. You said that you have cards for England and Australia? What about Canada? I would guess that there would probably be a better option.
Oh well, I've got to run.
