Okay, so Gary has been in the industry for an extremely long time. His experience spans over five decades, which is unusually long. Typically, interior designers and contractors with similar experience might charge higher rates. However, considering the fact that Gary has been in the same company (Gary Hanson Wallcovering) for so long, it's likely that he's invested heavily in the business. This could lead to a lower hourly rate. I'm estimating around $75 per hour, which is on the lower end of the spectrum. However, without more information on his specific skills, services, or industry demand, it's difficult to provide a more accurate estimate.
