Is Adobe Output ES3 right choice???

Hello,

My requirements are to generate pdfs based on inputs from watch folders, web services in xml format. I will have 100 odd templates for which pdfs are to be generated. Is Adobe LiveCycle Output ES3 right choice for it or I should look at some other module?

Also an interactive correspondence management solution is also required. Suggest what product I should choose.

Thanks and regards,

Mayank
