Amazon Ec2 Cloud

We have an application that we are considering putting on the Amazon cloud. We talked with a few people at ServoyWorld and we believe that this is the way for us to go. My question is this. Has anyone set up an AMI with Servoy already installed using Sybase as the database? We would need to use Sybase as the database and the only one that I have found so far is not using Sybase as the database. How hard would that be to change in the AMI if there is not one set up already?
