What about some sort of consultancy business? Something like events/wedding planning. I have a couple of good friends who have similar interests to you - one bought her own business (a florist), the other set herself up as a consultant/buyer for an associate's new fashion store. Both are totally in their element, however the earning side of things has taken longer to get established. Personally, I'd always rather be doing what I love that doesn't pay so well than be raking it in but doing something that makes me miserable.
