I second The Good Life's thoughts and suggestions. As well as the brands The Good Life mentioned, maybe you'd be interested in some of the more niche 'classic' brands like Creed, Caron, Annick Goutal, Acqua de Parma, Serge Lutens, Frederic Malle Editions des Parfums...
My very best suggestion to start you off exploring would be to go to Les Scenteurs (http://www.lessenteurs.com
) and browse through their stock, order yourself half a dozen that appeal to you and try them out without the expense of buying a whole bottle. They only sell good stuff - no tricksy brands that pay a fortune for publicity; in fact, you probably won't have heard of many of them.
And as well as giving you piles of reviews and descriptions of fragrances, the directory here at Basenotes lists the year a fragrance was introduced, so if you want to ensure you choose fragrances that have stood the test of time, you can.
I hope you find something that you love and can't live without.
