Bulk Email Sending

At the moment I have a list of around 100.000 email addresses that I want to send an email to. So, I'm looking for somebody who could do this for me. I will provide: - The email text (only text, no markup) - The email addresses in an Excel file - The email address that the recipients should see when they receive the email (before starting I would like to see one or two test emails to see if it's working) Please, tell me how fast you can do it, how much it will cost me and how you will do it.
