The transition office or career center can provide contact information. If you want a particular room, or exclusive use of the building for employment, be sure your agreement says so. Advertise such an event for several weeks beforehand in the campus or installation's newspaper and the papers that circulate in the nearby communities. There are more similarities than differences between college placement offices and military transition offices. Staff members have similar backgrounds and sometimes migrate from one type of office to the other.
Clients receive similar training in the usual range of job search skills.
Services are provided at no cost to either clients or employers. Staff are well-informed on the demographics of their client populations and can advise you. Here are the official military job descriptions for the Army, Navy, Air Force, Marines and Coast Guard.
