InDesign: Create PDF Droplet

I would like to create a Droplet that would create PDF’s from InDesign docs. - either individually or batch.

When a InDesign doc is dragged to the droplet…the the script would:

open the doc. in Adobe InDesign CS6
create a PDF using Adobe PDF preset.
save the PDF result to specific location on the network.
then close the doc.

all without intervention

sounds fairly straightforward but i am new to InDesign and not the best script writer (nor have i ever designed a droplet lol)

any help would be greatly appreciated - thank you in advance
