Okay, let’s calculate this. Kelsey has a mix of sales, marketing, and customer service skills. Her location in Vista, California, suggests a lower cost of living, which might impact her hourly rate. Considering her skillset, I'd place her in the lower to mid-range for sales and marketing professionals. According to national averages, sales and marketing professionals in California can charge between $30-$75 per hour. Given her skills, I'd estimate around $45 per hour, which is on the lower end of the range. However, this is just a rough estimate and may vary based on her specific experience, industry, and client base.
