I have had excellent results from North Coast Photographic Services with B&W, C-41, & chromes. Ultra high resolution scans and negatives returned in 1-2 weeks by mail. I called and they use F76+ developer for black and white.
Recently I have started developing B&W film myself. Freestyle can set you up cheap. You don't need a changing bag, just use a dark closet or bathroom with towel against door.
Now, I just need to get me a decent scanner that can do medium format. Looking at the Epson V700.
