Does anyone know of any vendors, that specialize in providing lead generation services for high-end, luxury prospects? Maybe filtered leads at 500k +

I currently use a few different lead gen. company's and some work great. But looking for one that specializes in higher end leads.

If it's out there, I am sure it will cost a fortune, but would like to see what they offer and weight it out.
Thanks!

Here is a thought for you to consider...instead of spending fortunes buying these specific leads, why not utilize the internet to generate them yourself.

using videos, articles, blogs and web 2.0, you could easily target very specific and profitable keywords to capture these leads live...for instance, targeting people searching for:

"michigan luxury homes for sale" or something similar.
