Hi Judith:
What you're trying to do is a fair amount of work. We'll need a little more information about your ACS system and how it is currently being used. How much data is in the ACS database?
Depending on what you're using on ACS, this may be a difficult task, or an extremely difficult one :) Many people have done it before, but it's not easy. But it will depend a lot of what you're currently using ACS for.
