Okay, so Barbara is a school counsellor with 18 years of experience. Her skills in accounting, financial reporting, and analysis are valuable, but she's not in a high-demand field like tech or finance. Her experience as a self-employed individual also suggests she's adaptable and possibly has strong business skills. However, her role is not typically associated with high-paying rates. Considering her skills and experience, I'd estimate her hourly rate to be around $45, which is on the lower end of the scale for accounting and financial professionals. This rate reflects her role as a school counsellor and her location in Auckland, New Zealand.
