You could try ABC (look under consumer services):
G King Photocolour (price list):
(NB. - no relation)
CustomColour (which is Lens & Shutter):
I've always had good results with ABC. The times I've used G King Photo I've been satisfied, and I think they may be slightly less expensive for low res scans.
Finally, and this may be heretical, but for 35mm colour snapshots I've had good Develop and Print results from the Queensborough Walmart, and a disk with low res scans is just $1.97 extra.
Hope this helps
