the problem however, is it will not be searchable after it is scanned in this manner. It will need to be OCR'd or it is just an image file in PDF format (no text).

For OCR, the Acrobat suite (acrobat Standard and Pro) has great OCR abilities, as does Scansoft from Nuance.

Most scanners that I have used will scan to PDF easily, it may require a preset, but the SW is there.
Also, another thing to try is using a Mopier unit or HP Digital Sender. These will scan to email and/or other places as well. The Digital Sender can scan to PC or email and has other functions (can program it to scan directly into a database), etc..

What scanner are you working with? It should have come with software to do just what you wish. Do tell do tell.

The most easy to scan documents to a PDF is using PDFScanner for Windows Mobile on your Pocket PC or Smartphone.
