1-bit depth works for all text that I've come across. Sometimes
8-bit or so helps with photos, but even there I used to scan in
1-bit and rescan those few pages that did not come out too well.
This may not be an option for you.
Once you have the final tiffs, you can convert to G4-encoded
TIFF (maybe they'll come that way anyway if you ask nicely,
worth a try since you are paying!)

Well c4topdf will turn G4 encoded TIFF into multipage PDF. It may
turn non-G4 TIFF into G4-TIFF on the fly too, but if it does not,
then ImageMagik will (but seems dreadfully slow to me).
I used Acrobat 5 to do TIFF->G4-TIFF and Acrobat 4 to do multiple
TIFFs to one PDF, but then I was doing this in the office so I
didn't have to shell out for the s/w.
Here in the UK, A3 (really 11x17) scanners are coming down to
reasonable levels. It might be cheaper to buy a scanner and
stand in front of it for an hour than pay commercial rates
to get the job done. Even better, you might find someone
on list offering to do the job if you pay the return
postage (I'd offer but I'm (probably) not in the right
continent and, more importantly, I no longer have access to
a suitable sheet-feed scanner).
