Okay, let’s tackle this. So D. Alhadi Alkilani has an extremely long tenure of 66 years in architecture, which is unusually long. His PhD from the Technical University of Budapest adds significant prestige. Skills like Sketchup, Photoshop, and 3D Studio Max are in demand, especially in architecture. Location is Libya, which might affect the rate due to regional factors. Considering his longevity, education, and skills, I would estimate his rate to be on the higher side. Top architects can charge $200-$500 per hour, but his unique experience and education might justify a rate of $250 per hour.
