I'm in charge of generating leads. These are not hot leads ready to take action. They are lists of emails and numbers of people related to a particular industry. Real estate, JOB leads , people needing legal services, medical and more (separate lists of course). I'm looking for a partner who can offer these contacts to target buyers (real estate agents, medical centers, attorneys) or someone who does mass mailings and has the right offers. Most leads are US residents.
