US Consumer Email List for Lead Gen

I am in need of a highly targeted email list for lead generation. The list should be specific to US consumers falling in particular age groups and income levels. The location of these consumers is also crucial. Ideally, I want individuals who are mainly associated with the health and wellness industry. Expertise in data mining, marketing research and possessing a rich database for such demographics would lead to successful completion of this project. A deep understanding of lead generation techniques is also desired.
