E-mail Spider Pro needed

I need to find the e-mails of all the users of Aweber, Infusion, Constant Contact, Swiftpage, GetResponse, and 1SC. These are e-mail follow up programs. Please give me details on what you can do. I need to be confident that you can do the job. Tell me how many people you think you can get (Aweber suposedly has over 45,000 users), and what it will cost.
