Certified PDF (Pitstop , Instand PDF etc.)

At the moment i'm creating brochures via Indesign Server. After I save the document to indd I want the document to become a certified PDF which is ready for printing.

Is it possible to install Instant PDF and just save via Javascript as Certified PDF ? Or do I have to buy pitstop server and save my indesign file as pdf to a Pitstop Hotfolder ?

Hope someone can help me!

Thanks in advance!
