Michael, I worked for a county as a grant writer for several years. Although I had success in several programs, I didn't come up with anything specific for veterans services. We did have some success, however, with a large federal HRSA grant involving 28 agencies and the county. The focus of the grant was coordinating indigent health care. I'm not sure how much help it has been to the veterans services unit, but they do use it.
Seems like there ought to be a professional organization of county veterans services with interest in this challenge on a national basis. Good luck.
