Worthwhile Linux Certifications

I know enough about Linux to be dangerous, but my goal of taking a hobby and getting paid for it has been out of reach. I have never been about to make the leap to a full time job. I have been looking for a Linux certifications that is worthwhile. to take. I don't know if they will help or what is out there to take (besides RHCE). Any suggestions?

Also where are places to loo for work experience?...is this better then getting a cert?
