Greetings!
After looking at a few pages of posts on your Instagram page, I would say there are several things you could incorporate into one business. Thinking outside the box, I would say find and establish relationships with car dealers, real estate agents, etc., as well as personal owners, and discuss rental options with them. You bring them clients (who get a certain discount) and they pay you a business service fee in return. If I want to rent a lambo in San Diego, I call you and you set up the appointment for me. This can work with cars, houses, time shares, even jewelry. Anything that can be rented can be available. It's just a matter of finding the supplying source(s).
Other ideas that come to mind are tattoos, shirts, stationary, autographed pictures, paintings, custom screen savers, mouse pads, vision/dream board creation services, private charters (yacht, airplane, etc.), and vacation package deals to name a few off the top of my head. If I were obsessed with luxury items, I would want to be surrounded by them as often as possible and/or have access to them whenever I want.
Find YOUR true passion. Think of how and where you want to spend your days. Carefully and seriously focus to imagine yourself already doing those things, then reverse engineer the steps it will take to get there and you will have a general plan of attack to start from.
I hope this helps. Take care and best of luck!
Daniel
