Hi, I suggest to click on these links to check out the interior designers that have done work in the Miami area.

Start an ideabook here on Houzz and save any of the photos of the projects you like. Many of the pictures will be labeled as to which interior design firm worked on that project. I would probably then compile a list of those designers whose worked you've saved in your ideabook and start with researching/contacting those firms....maybe start with the firms that you've saved the most pictures of in your ideabook.

PS Having an ideabook is a good tool when you hire a designer. You'll then have something you can easily share with whomever you interview/hire that'll give them a good idea of what you like.

To help you out a bit more, these are the same links but filtered out to show only projects that were labeled as higher end/higher dollar projects ($$$ and $$$$) since you mentioned your home is higher end.

I think I would stay away from the rustic in either case as neither one looks high end to me.
