boatbooking site

Our application is a self designed booking system for ships. It is php based and works with a mysql database. ? The systems works as a CMS for the different websites and contains several booking possibilities The system is up and running and needs some additional features. ? One of our wishes is to expand the number of auto generated emails. Further we would like to make the system ready for using more languages. It is a system which is "on the move" all the time. We would like to start with the implementation of the auto email functions.
