Need Your Advice.

Hi everyone,
I recently completed the Oracle 10g DBA training and am preparing for the certification exams in a week. I am very interested in a voluntary / internship role where I can get some real hands on experience as a DBA.I'm a graduate,but have not done any DBA work. I believe this experience would give me a good path back into the workplace and into the role of a DBA. Can anyone advise?
