35mm scans, Boston-Providence area?
 

I'm wondering if anyone has any tips on a trustworthy scanning company for 35mm slides.
All I have is an Epson V370, which is competent, but no ICE, and only 4 slides at a time.
Although I'd like the potential gig, I simply do not have the ability nor truly proper scanner for a few thousand slides.
I dream of getting a V600 at least, but even with ICE there is still the limitation of just a few slides at a time.
So my fellow forum friends...any recommends? I'd like to give this woman proper advice.

EDIT: She was hoping to go thru them so eliminate unworthy slides, but even that could prove to be a monumental task.
