Okay, let’s tackle this. So Sarah has skills in marketing, sales, customer service, and merchandising, which are valuable in the beauty industry. Her experience in cosmetics and retail is also relevant. However, without specific numbers on her experience or education, it's challenging to estimate her hourly rate. Typically, entry-level marketing and sales professionals in the beauty industry can start around $25–$35 per hour. Given Sarah's skills and experience, she might be able to command a higher rate, but without more information, it's difficult to pinpoint. Let’s assume she’s in the mid-range for her level of experience. Maybe around $40–$50 per hour. So I’ll estimate around $45.
