You may want to order some samples from The Perfumed Court (www.theperfumedcourt.com) - especially if you looking for fragrances that are not mainstream. They have different sampler packs based on experience level, different notes, etc. It's a good way to experience a wide variety of different/unique fragrances.
Although it sounds like you may like something from Serge Lutens.
Good luck with your search!
