rename file from PDF data

I have several thousand PDF invoices. I want to rename the files using the data in the Name field to rename the file in the format "invoice - (invoice number) - (name).pdf". In other words, read the customer's name from the PDF and append it to the end of the filename. Interface and programming language don't matter, but it needs to be able to process all the files in a directory. Attached is a zip of the two types of invoices that I have. Either the program needs to work with both, or two different programs. I don't care, I just need to accomplish this task. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
