Okay, let’s break it down. Jina has 13 years of experience as a laboratory technician, which is a solid foundation. Her skills in water quality and fisheries are in demand, especially in the Philippines. However, considering the role is a laboratory technician, not a senior-level professional, and the location is the Philippines, I'll estimate her hourly rate to be on the lower side. Typically, laboratory technicians with similar experience and skills in the Philippines can charge around PHP 15,000 - 20,000 (USD 300-400) per month. Let’s assume an hourly rate of USD 25-35, considering the exchange rate and industry standards. I'll round it to USD 75 per hour.
