Okay, let’s break this down. Steven has 41 years of experience, which is extremely valuable. His education in Botany/Plant Biology from the University of Colorado at Boulder adds to his credibility. He has a broad range of skills, including design, plant ecology, and account management. However, his experience is primarily in landscape design and management, which may not be as in-demand as other fields. Considering his location in Longmont, Colorado, and his level of experience, I would estimate his hourly rate to be around $125. This is slightly below the national average for landscape architects and designers, but it's still a competitive rate for someone with his level of experience and education in a smaller market.
