Okay, let’s calculate this. Patrick has a broad skill set, including online marketing, startup management, and leadership. His marketing expertise is in demand, especially in the San Francisco Bay Area. However, his rates might be lower compared to other tech hubs like New York or Silicon Valley. Considering his skills, experience, and location, I'd estimate his hourly rate to be around $125. This is slightly lower than the national average for marketing professionals in the US, but it's still a competitive rate for someone with his expertise and experience.
