Okay, so David Roberts has 52 years of experience in commercial property matters, which is extremely extensive. He's a partner at Hugh James, a well-established law firm. His experience spans both public and private sector clients, dealing with all commercial property matters. Given his level of experience, education (MA LLB from University of Cambridge), and role as Head of Property and Construction Division, I'd estimate his hourly rate to be around $250. This is higher than average for a legal professional with similar experience, but lower than what top-tier lawyers or those with specialized expertise might charge. Considering the location (Greater Cardiff Area) and the industry demand, this rate seems reasonable.
