PDF Automation

I am trying to automate multiple steps:

Step 1: Extract Pages from a Dynamically Generated PDF

Step 2: Open pages one at a time

Step 3: Search for and copy first two words on the page (LAST NAME, FIRST NAME)

Step 4: Rename file with "Date"_"LAST NAME, FIRST NAME"

I looked into other options and saw that Adobe Bridge has a batch renaming feature.

But it can only pull from metadata, so if I could automate the "LAST NAME, FIRST NAME" being copied into the Keywords Metadata that option would work.

Any help on this would be appreciated
