Amazon Ec2 and LAMP configuration help

We need someone to help finalise the configuration of a LAMP server based on Ubnutu running on Amazon EC2. We have used a pre built AMI to make the instance and need some help with some final tweaks. You will work with our webmaster to finalise the server config and make a snapshot of it. Tasks include - Finish configuration of Postfix and spam assassin - its all installed just needs some configs entered. Move domain to point at EC2 - we have a zone edit account that can help the configuration of this. Install an Open Source web hosting manager like cpanel. Configure SSH tunnel so that Navicat and Mysql admin tools work remotly. Change all the passwords on all the servers. Make a snapshot of the server. We are moving to Amazon ec2 as our hosting so in the future there will be more work for you if you are good on this project. You must have at least 5 years *nix experience and having good php skills is also a must because in the future we would need some php hacks made to scripts. You must speak fluent English and use skype to communicate. Think of this project as a test so that we can see if you can work with us in the future.
