Based on Nathan's skills and experience, I'm estimating his hourly rate to be around $75. This is a relatively conservative estimate considering his role as a landscape designer, which may require both creative and project management skills. However, his skills in Microsoft Office, Photoshop, and social media are more commonly found in office settings, which may impact his earning potential. Additionally, his experience in customer service and public speaking can be valuable in various industries, but may not command the highest rates. Given his location in Dallas, Texas, I've also taken into account the regional market rates for similar positions.
