I've found - after trying several apps and custom scripts to do OCR - that the easiest most convenient solution is to just get a printer/scanner combo that does the PDF & OCR directly in hardware. That usually means something targeted towards SMBs that works standalone (in my case a Canon). I.e. specifically not a consumer device: the consumer units usually rely on separate client-side software for doing the OCR processing which complicates the workflow.
