Okay, let’s tackle this. So Prem Nath has 57 years of experience in architecture and management, which is extremely rare. His education from Sir J.J College Of Architecture adds prestige. Skills like architecture, management, and project management are in demand. Location is Mumbai, India, which is a growing city with a high demand for skilled professionals. Considering his extensive experience and education, I would estimate his hourly rate to be around $200. This is slightly lower than what I would expect for a Chartered Engineer, but architecture and management skills are highly valued in India. Some top architects and managers can charge $300-$500 per hour, but Prem’s unique combination of skills and experience make him a rare talent, justifying a lower rate.
