Given Harley's limited experience and lack of specific skills or education mentioned, it's challenging to estimate a precise hourly rate. However, considering his role as a Business Professional, a general estimate for entry-level or junior professionals in the UK could range from £25-£50 per hour. Let's assume an average rate of £37.50, which is a rough estimate for a 0-2 years of experience professional in the UK. This rate is also influenced by the industry average, location, and the company's size and type. For a more accurate estimate, more information about Harley's specific role, industry, and location would be needed.
