Okay, let’s break it down. David has a broad range of skills, including strategic growth, team development, and public speaking. He’s also worked in various industries, including non-profits and events. While his skills are valuable, they’re not particularly rare or high-demand. I'm estimating his rate around $125 per hour, which is on the lower end of the scale for someone with his experience and skills. This is partly because his location is Kansas City, Missouri, which may not be a major hub for his industry. Additionally, his skillset is quite broad, which can make it harder to pin down a specific rate. However, considering his experience and the fact that he’s been a featured speaker, I think $125 per hour is a reasonable estimate.
