Considering Collette's experience, skills, and education, I estimate her hourly rate to be around $150. This is based on average rates for financial professionals in South Africa, taking into account her role as a Financial Manageress and her certifications from reputable institutions like the South African Institute of Chartered Accountants. Her experience in accounting, taxation, and business administration also justify a higher rate. However, without specific industry benchmarks or location-based data, this is a rough estimate.
