First, I'm not a sir. I'm a "ma'am", hehehe. I think Medicall is located at Makati, I don't have the exact address but you can try checking google for their contact info. I heard the pay is good, esp for NCLEX passers.
You may want to checkout NARS program (they need 5,000 nurses for Batch 2) if you want to practice nursing. The pay is not that good (P8k/mo) compared to Call Centers (ave. of P18k/mo), but you get to practice your profession. Another catch is that you will serve for 3 months in the rural community setting and another 3 months in the hospital setting. All in all, NARS is a "golden" oppurtunity for us nurses. BTW, one of their requirement is that the applicant should not have any nursing experience, so this program is tailor-fit for newly registered nurses. Start of employment is on Oct 2009, so if your interested apply online asap (http://www.nars.dole.gov.ph).
