Digital BW, The Print

Would anyone care to recommend a reputable, good quality scanning service either in the SF Bay Area (preferrably) or elsewhere? I have quite a few B&W 8x10 prints I would like to have scanned with the intent in some cases of going up to the 13x19" limit of my Epson 1400. I'm familiar with Cantoo locally, but can't afford $50 per image (even if it is 10MB) for more than a few of these. Any recommendations or advice will be greatly appreciated. Thanks.
