I ran across this article from Ted Landau (Senior Contributor for Macworld, etc) trying to compare NeatDesk for Mac and ScanSnap S1500M.
The Neat company basically does not only make the hardware scanners, but they also developed a software capable of doing OCR and some file management. The software is called NeatWorks ($80)—come bundled with scanner and also sold separately from hardware.
According to Landau, hardware-wise, he prefers the ScanSnap S1500M, but the software-wise, NeatWorks is better. So to have the best of both world (and if you have some extra cash), he recommends getting the ScanSnap (and you'll get Adobe Acrobat Pro for free anyways)
and the NeatWorks.

That's some thick texts you've got!
Anyway, our campus has a copy center that basically refuse to do service of scanning textbooks (although I was told that the service may be available to Disability Resource Center students)—copyrighted materials issue.
Then I tried asking FedEx Office (used to be called Kinkos), they said they would do digitizing (although I didn't really mention about textbook, but the staff saw me holding a 1000-page textbook), but with the cost of $1/page.
That would be $1000 just for one textbook.
I've also looked into a couple different online service that will do this particular service for you. But they are still expensive if you consider about doing it quite frequently in the future as well.
So, I think it's much cheaper if you actually invest on a really good scanner like the ScanSnap S1500M (for Mac) for about $400 and you can always use it for future texts as well.
