I mentioned the PMI website http://www.pmi.org
PMI has everything you need to get started.
You will need to complete the application. You can do it on paper, but doing it online is so much easier.
The application takes time and may take several sessions to finish. (You can save your work and come back to it later).
After PMI approves your application, you need to pay for the exam and schedule it.
There are Prometric testing centers all over the place. I'm sure there is one not far from where you live.
