What type of job fair is this? If it brings employers and applicants together, they don't charge the jobseekers. If it's a training seminar, you really need to research it to determine if it's worth the cost.
A Master's in criminal justice in homeland security should be a slam dunk for you in the job market. I'm surprised you haven't been recruited already.
Best of luck!
