The CCNA is such a low-level cert that you seldom see jobs that call only for that credential. You'll want to look for anything you can find--probably help desk, tech support, network technician, or junior network administrator--that lets you develop some practical skills and knowledge in the networking area. Though you don't mention a college degree in your e-mail, such a credential might also be helpful in positioning yourself for a job.
However, a CCNA by itself is generally not enough certification to put you into the workforce, without other degrees, credentials, or experience to back it up. If you aren't able to find work, you might want to consider entering a network training program of some kind, or pursuing professional level Cisco certs (CCNP and CCSP are probably good targets to consider) to put yourself into a more employable posture.
