have you tried to contact fuji labs or dwaynes ?
when i was shooting a lot of 8mm ( and 16too) i would drop rolls off at
wally's for like 2-3$ / roll and they would process them for me, and did a great job too.
you just needed to write in the "special instructions box" 8mm ( or whatever ) movie film.
there is also a movie film lab in s/e massachusetts, http://cinelab.com/ maybe they can process your film too ...
Dwayne's does not do b/w reversal. Cinelab does, but they won't touch Fomapan.
