Not sure when the next one will be, but AFS http://www.afsvision.com/Careers/Career-Opportunities sporadically holds a Cobol training academy, where they pay individuals to learn Cobol for a few weeks, and generally hire a majority of them.

The exton, PA location is also close to Lancaster PA, so rural living is an option. I only use webservices with that group, so our corporate recruiter would probably have a better idea of what's available.
