Luxury consumers

We are targeted in luxury brand consumers, and our major market is in US (it covers all states in US). In order to promote our brand, we would like to get some direct customer access (DCA) in email in US which maybe find in internet or existing database. Our initial target is 5,000 - 10,000 DCA which may be members in luxury products or fine jewelry products. Extra bonus would be provided if those information is valid and useful.
