Admin Task - Scheduling Emails

I would like someone to schedule up some emails into 2 auto responder accounts. The emails to use will already be in there, it will be a matter of pressing a button to duplicate the email, set a date & time to go out and a couple of other fields before saving the message. A document detailing the process and all details required e.g. login information, from name, email address etc will be provided. Please specify in your bid how many weeks worth of mails you will schedule up. There will be 12 emails going out in a day on each account.
