To take either the CAPM or PMP exam, you need a combination of work experience, training, and knowledge (as measured by an exam). There are many avenues and nearly every college offers some form of project management education. I got my start with a company that offered on the job training. So I think your next step is to download the certification handbooks from PMI.org, see what the requirements are, then determine a course of action that will help you meet them. You might also start networking at your local PMI Chapter (and you can find that at PMI.org as well). Good luck -- keep us posted on your progress and post any additional questions.
