Bulk Email Sending

I have an excel database of approximately 1,000,000 prospects. I need someone to email the database for me, and in the process remove the bounce-backs/bad addresses. My small tests of the database have shown about 30% to be bad addresses. The list does not need, and in fact should not be, mailed all at once. Spreading the project over two weeks would be fine, even desirable. The text-only email content will be provided by me. You must be able to reference, within the body of the email, fields provided by me, such as: "Dear FNAME, I hope the weather is nice in CITY", where FNAME is a field within the list and CITY is a field within the list. The email must include an automatic unsubscribe or opt out feature in the footer. You must be able to remove from the list the bouncebacks and the unsubscribes. You must also be able to track the click-throughs and automatically update my database so I know who clicked through the link to my site. In your bid, please specify the quantity of email sent and the expected time to delivery for your bid. Additionally, bidders who provided detailed information about their experience with bulk mail, techniques for balancing the load of the email across multiple servers, and how the bounce-backs will be processed will be given full consideration. Successful bidder will have the opportunity to handle recurring work of the same nature. This is the third time I have posted this job. Previous vendors were unable to complete the task or were unable to do so satisfactorily. I will give you one week to begin sending email and two weeks to complete. If after the first week you are not sending email and cannot provide proof of this to me, then I will cancel the project. I will escrow the full amount of your bid upfront, and release it when the project is complete and you can deliver the data to me.
