Apache + mysql/SSL/PHP/etc. install req on Linux (difficult)

I have a Linux box running Redhat 2.6.9-42.ELsmp. It already has Apache2 installed in /usr/local/apache2 I need Apache2 installed with SSL/Mysql/PHP etc. so I can mirror the current setup, but in a SEPARATE directory. I.e. I need 2 instances of Apache2 to run, one normal, and one over SSL. A new compile is required, but the current LIVE apache2 instance is not to be touched, and nothing should stop the live site from working. There appear to be issues with just compiling Apache2, so you'll REALLY need to know what you are doing - otherwise you'll just be wasting your time and mine. Any downtime with the live apache will mean no payment to you. Make sure you know what you are doing before taking this up. The current live site runs with PHP/Mysql/etc. I'll provide the winner with the URL and account + passwds.
