Hi Skipper,
We have an Amazon Web Services Price Calculator embedded on our site that can help:
http://www.cloudcontrollers.com/bill...ice-calculator. But there isn't much to it- there is no data to move, just create and instance, launch the instance and start configuring it.
However, adding EBS volumes to prevent catastrophic config and data loss is vitally important. As there is limited help on this subject in this forum, we will be publishing our best practices setup for this server soon on our site- hopefully before the leaves turn

If you are not familiar with how to create mounts on a Linux system, symlinks for directories, etc you will need someone with Unix/Linux skills to assist you.
Thanks to Eric's work on this, we were able to jump into FreePBX and Asterisk painlessly, and our modified instance of this AMI has been running non-stop for Cloud Controllers in the US West region for about one year. All for the cost of about $70 a month in server charges plus VoicePulse phone charges.
VoicePulse is a very reliable termination provider and you can get $10 free credit to test the service:

They also have a module you can install in FreePBX to make administration easier.
If you need help configuring and supporting this PBX we hope to begin offering support soon (again, before the leaves turn) - you can PM me your contact info or sign-up for our new applications mailing list at our site.
Best Regards,
