I need the ability to create dynamic forms, text fields that grow, visibility rules. Where do I start?

I work for the Department of Child Safety for the State of Arizona. I generate 100s of forms per year and it the inability of form fields to "grow" with available content has become an issue. What software do I need to look at and present to my directors and the I.T. staff that will allow me to do this? Is it possible to still do this within a PDF framework, XFA forms? Livecycle seems to be dead and AEM seems to have replaced it but I am not sure if AEM is web-based only now? There is a heavy print component of this process as collected data needs to be printed in instances such as court appearances etc. So, Where do I start?
