Develop E-Mails LIsts

Our company does professional development training for staff and administrators from USA public and private schools (k-12), non-profit organizations, colleges/universities, local & state government agencies, libraries, and religious organizations. We are looking for a company that can offer us lists that contain e-mail contact information for the audiences we have described above. These e-mail contact lists must be clean and recent. We are looking for e-mail lists that total over 1 million e-mail addresses. These e-mail lists can be from any of the audiences we have described above. We are looking for a long-term relationship with a company that can supply us with e-mail addresses from these audiences on a regular basis. But for now, we are interested in a quote for an e-mail contact list containing 1-million or more e-mail addresses. If you have the capability to do email marketing, we would like to know about that also. We might ask you for a quote on doing the email marketing for us, in addition to furnishing us with the e-mail contact information.
