Postfix mail server as script on AWS

I need a installation script to run on AWS EC2 Debian based server Which will install postfix and dovecot, that script should read : hostname, mysql, and whatever else parameters it need to adapt and to start execute mailserver role I have mysql DB created by postfixadmin I will provide credentials to that DB so you can test your script So goal is to get a script which can be run on fresh AWS EC2 Debian instance. That script should install postfix and dovecot and cofigure them according to User Data set for that instance: mailserver hostname, mysql DB to connect and read accepted virtual domains and mailboxes to serve. Please don't ask for any advance payment. I will start any discussion once you have script and server ready and connected to my MySQL DB. That way I can check if script is working without getting source code yet. That means you shouldn't worry that I will take it and start using without payment. So when you are ready to demonstrate that everything is ready - I will provide you MySQL credentials to connect. And I will set up few test accounts there and will test dynamically if mail server is working. If it works I will pay you 50% and ask for script source code. Then I will test it on my EC2 to see if it can automatically read User Data from EC2 settings when install. And if it works - I will pay you second half of money.
