A great Noodle article for helping you figure this out is "How to Apply to Grad School in 10 Easy Steps." As someone who is currently applying to graduate schools, I can attest this article provides good advice.
You can also utilize Noodle's grad school search to find schools that offer a master's program in your field of study. It is likely you have some chosen criteria of location, budget, etc. that already narrows down your search. Once you get a proper list, take a look at their programs online. Often programs provide statistical information about their typical grad student including mean GRE scores, GPA, etc. And don't be afraid to contact the schools directly to ask questions that can help you discern if they are right for you.
But above all else, don't shortchange yourself! Based on your strengths, personal history, statement, resume and work experience you might be a perfect candidate for a program you wouldn't otherwise think you would be. Take a look and see what different grad programs want from their candidates. You might surprise yourself. Good luck!
