Okay, let’s calculate. Nichole has a mix of skills in accounting, finance, and business intelligence. Her location in Tulsa, Oklahoma, suggests a lower cost of living and doing business compared to major US cities. Considering her skills and education, she could potentially charge a rate comparable to entry-level finance professionals in her area. However, without specific industry demand or experience in a particular sector, I'll estimate a conservative rate of $75 per hour, which is on the lower end of the scale for finance professionals with similar skills in the US.
