Okay, let’s tackle this. So Chris Mitchell has a strong background in architecture and sustainable design, which are in demand. He's also LEED AP certified, which adds to his value. Location is Miami, Florida, which is a hub for architecture and design. According to the Bureau of Labor Statistics, the median annual salary for architects in the Miami-Fort Lauderdale-West Palm Beach area is around $80,000. However, considering his expertise and certifications, I would estimate his hourly rate to be around $125. This is slightly higher than the median salary, but lower than what top architects in the area might charge. It's also worth noting that Chris has experience in management and project coordination, which can command a higher rate. However, based on the information provided, $125 seems like a reasonable estimate.
