Okay, let’s tackle this. So Sara has 22 years of experience in customer service, which is a long time. Typically, customer service professionals with this level of experience can charge higher rates. However, without knowing her specific skills, certifications, or industry, it's difficult to estimate a precise rate. Generally, customer service professionals with 20+ years of experience can charge $25-$50 per hour. Considering Sara's experience and location, I'll estimate a rate of $25 per hour, on the lower end of the range.
