If you're unemployed (or under employed) I suggest putting your resume on as many job sites as possible. The service is free (usually) to job seekers. So, there's no out of pocket for you and it gets your information into the hands of potential employers.
The link below lists 50 of the top online sites to post your resume:

The majority of the jobs I have gotten in my life (even now in this economy) was because I post my resumes online and employers CALLED ME to interview with them, rather than the other way around.
Many of the sites will let you just upload your resume, and others are a bit more tedious because you have to key everything yourself.
Best of luck to you in finding your dream career.
