Hello Lee Ann,
Your best bet would be to reach out to your CEx and/or Account Executive to track down some of that information. They may also be able to organize a demo for you with one of our Solution Consultants to help you with your request. If you do not have contact with either one of those individuals above I would be willing to forward your contact information over to one of those teams to provide you assistance.
