Digital BW, The Print

A friend has asked me how to scan a lot of older BW negatives he has 
recently obtained. This isn't a topic I know much about, but I do know there 
are several of you here on the list that could offer suggestions. Here's 
what my friend is asking about.

Regarding the negatives ... there are hundreds ...
they have been stored in little envelopes but have
been handled a lot so aren't particularly clean ...
the majority are approx 3 1/4 x 2 1/4 although some
are 2 1/4 by 2 1/4 ... for my purposes a contact sheet
would almost be okay, however, that process wouldn't
produce very good finished results so guessing I'd
need to have 5 x 7 prints made up, one each, probably
in groups as I can afford ... wouldn't mind sending
them off, but am probably more nervous about this ...
would be nice if it was within driving distance ... I
know that there are scanners that will do negatives ...
perhaps I need to look into one of these but not sure if
they are able to do these large format negatives or just
35mm, of which I have none.

We're in Indianapolis and will appreciate your suggestions. If I haven't 
provided enough info, let me know what else you need in order to offer 
constructive suggestions.

Thanks...
