Help finding scanning service

Hello all,

I have ~20 rolls of APS film and want to have them scanned in as high
resolution I can for archiving/etc.  I would rather go through a service
(vs. buy a scanner, manually scan, end up with a scanner I won't use after
this, etc).

I found one service that will scan APS film: www.photoworks.com who will
scan up to 1500x1000.

Many places won't do APS, or if they do, are in low-res.  Some places just
don't give up the facts, like what resolution you end up with, esp.
specifically for APS.

Does anyone know of other places that will scan APS film, at higher
resolution?  Thanks in advance!
