Separate VB app to talk back to a Web Service

Customer sends XML data to our Web Service. Web Service does some
data transformation and puts the data into a special format that
another application uses. That data is in a file.

This other application continuously polls a folder for these data
files and processes them. It eventually creates a PDF out of the
data with a unique file name.

Web service needs to know when this other application is done
processing this data so I can send a URL of the created PDF back to
customer.

What would be the best way to do this? I don't want to sit there and
poll a folder for the output file, as we may have up to 40,000
requests / day.
