Showing latest filename in a folder -looking for ideas

Hi!
I am very pleased with Hazel - ie looking for patterns in a pdf and renaming them accordingly is such a 21st century move.
I have a folder with purchase orders that have incremental names. When I create a new purchse order (sometimes it's a pdf form the order confirmation of the website or some other source) I have to name it incrementally. So I go to the folder and check the latest file there.
Has someone already thought about a solution to automate that? Ie keeping a folder or .txt on desktop with the name of the next increment? Integrating with Tot.app to paste it into a tot text file? In the past I would have liked to use it with the dashboard post-its for example.
Cheers,
Paul
