I`m the one who recommended one of the Sloan Brothers` recent "Cool Companies of the Day" - Foot Petals. I`m a user of the product and learned about the product through various pop-fashion magazines I read.
She got a bunch of celebs to use her product and allow their photos to be used on her website promoting the fact that they use the product. I`m sure it`s made a big difference for her product sales.
Now, to your question: how do you get access to high-profile people? Well, I imagine there are stylists, agents, managers, friends of friends, etc., who know have contact with celebs. Maybe you should seek contact with people who know people, and that way you`ll get your product in front of them.
As for affluent people--people with money--that`s a different story. I know the Sloan Bros wrote an article about Networking with the Money People, and that might be helpful for you to read.
