Okay, let’s tackle this. So Hervin Romney has a Master of Environmental Design and Bachelor of Architecture from reputable institutions. He has been self-employed for 52 years, which suggests a high level of autonomy and expertise. His skills in architectural design, planning, and sustainable development are in demand. Location is Miami, Florida, which is a hub for architecture and design. Considering his experience, education, and skills, I would estimate his hourly rate to be around $150. This is slightly lower than what I would expect for a Principal with similar experience in a larger firm, but his self-employment status and location suggest a more flexible pricing model.
