Okay, let’s break this down. Dr. Olatunji has a Ph.D. in Environmental Engineering from a reputable university, which adds weight to his skills. He has 18 years of experience in project management, research, and strategic planning, which are in demand. However, his role as Chief Procurement Officer and Regional Music Director at Mountain of Fire and Miracles Ministries might not be directly related to his engineering background. Considering his location in Port Harcourt, Nigeria, and his industry experience, I estimate his hourly rate to be around $125, which is slightly lower than average for environmental engineers in the US. This is because his role seems to be more focused on project management and procurement, rather than pure engineering. Nevertheless, his Ph.D. and experience still make him a valuable professional in his field.
