Install, configure and setup Posfix, Dovecot and MySQL on Ubuntu Server

I need a Linux expert to setup and configure a multiple domain email server, aliases, virtual mailbox delivery to assigned domains. Server is Ubuntu 12.04 LTS x64. I will need the root, cron and any localhost accounts that are used by system processes to be mapped to and delivered to my google address. I would also like the postfix mailbox GUI manager installed and functional. Please be prepared to write a document to describe the steps you took and the packages installed or removed. This is a production server that is serving 30+ Wordpress domains with traffic so I expect zero down time. Yes all files are backed up and well as the data. Please bid on doing this today and testing/payment within 2 or 3 hours. SSH access will be given to winning bidder. Please put "I will setup your mail system" in the first part of your proposal. So I know you have read this and understand what I need to be done. INCLUDING the setup guide for future installations.
