Okay, let’s tackle this. So Marie has 21 years of experience in event management, which is a broad field with many applications. Her skills include event planning, corporate events, marketing communications, customer service, and social media. She's been running her own business, Chesha's Flowers & Accents, for 21 years, which suggests she's a strong leader and entrepreneur. Location is Union City, California, which is a relatively high-cost area. Considering her experience and skills, I'd estimate her hourly rate to be around $75, which is on the lower end for an event management professional with her experience. However, this is a rough estimate and may vary based on specific circumstances.
