Mailing List - Throttled Emails - Custom Solution

Hello, I am looking for someone that can help me setup a mailing solution to send out emails to the members of my site. I would like to be able throttle the emails to stay under a 400 message/hour rate. I need to have reporting to show when the message was sent, if it was delivered ok, and if it was read or not. The more features that can be included the better. If someone can't help me put together a solution for this then I might just sign up for a service such as constant contact. Hope to get started on this ASAP! Thanks, BCBC
