Okay, let’s tackle this. So Mark has a broad range of skills, but they are mostly in the event planning space. The rate for event planners can vary widely depending on the location, industry, and level of experience. In the Bay Area, event planners can charge upwards of $100-$200 per hour. However, Mark's skills are more general, and he doesn’t seem to have a lot of experience in high-end events or corporate planning. He’s more of a generalist. Considering his skills and location, I’m estimating a rate of $75 per hour, which is on the lower end of the scale for an event professional in the Bay Area.
