scripy to create jpg from pdf with page number and code appended to filename

I have only occasionally used acrobat scripting, i pick it up and then drop it so it is forgotten in no time.

I need to export as pdf as a jpg with a variable code entered via a dialog etc(eg. Test) and the page number (ideally in format with lots of leading zeros ie 00001) with the bookmark for that page eg."BookmarkName1" appended to the end so the end result would be

Test000001 BookmarkName1.jpg

Test000002 BookmarkName2.jpg

etc etc

Could some bright spark show me the code to do this? I could sling you a few bucks for a beer.
