The closest good B&W labs I know in your area are in Chicago.
The Print Lab is dedicated to only B&W film - http://www.printlab.com/
and Gamma is a full service pro lab http://www.gammaphoto.com/
I don't know if either do 'mail order' exactly, but I'd give them both a call. I'm sure you can mail them the film and make arrangements for prints to be mailed back.
