Well, if Marketing and HR is what you are open for, I'd personally choose Human Strategic resources management, as this has more of a psychological element, which I enjoy. Marketing is good enough too, psychology is involved slightly, understanding your customer is a invaluable task to any firm.
As for remuneration, it all comes down to one standard after a few months, or years at most. So don't chase behind a few extra bucks that only last for a few months and compromise what you'd love to do.
