Most jobs are filled without advertisements. In 35 years of working I got a job from a resume once - the rest were through contacts. My advice is to start going on information interviews. Seek out firms or agencies where you want to work, dig around and find someone in your field, and ask them out to lunch, coffee, or a meeting at the office. Just explain you are a recent grad seeking more information about the field, what it is like to work in the area, and how they like their work. People are glad to talk about what they do and more often than not will suggest you talk to someone else. And always ask who they might suggest you talk to.
I get these types of calls from youngsters regularly and take the time to meet with the because I look at it as returning the professional favor granted to me. As a supervisor when I need to hire the first thing I do is check with my staff to see if they know someone looking. Good luck.
