I'm estimating Lisa's rate based on her extensive experience in wedding planning and event management. Considering her 43 years of experience, I'm comparing her to industry benchmarks for experienced wedding planners and event coordinators. Average hourly rates for wedding planners in the San Francisco Bay Area range from $50 to $150 per hour. Given her extensive experience and expertise, I'm estimating her rate to be on the lower end of this range, around $75 per hour.
