Okay, let’s tackle this. So Michael Rigg has been managing director at the Scottish Writers' Centre since 1944, which is an incredibly long tenure. His experience in cost and financial accounting, financial analysis, and managerial finance is highly valued. Considering his location in Lancaster, England, and his industry expertise, his rate might be on the higher side. Let’s consider average rates for finance professionals in the UK. According to various sources, finance experts with similar experience and qualifications can charge between £200-£500 per hour. However, given Michael’s exceptional tenure and leadership skills, I would estimate his hourly rate to be around £250-£300. This is slightly higher than the average, but reflects his unique value proposition.
