Based on the skills and experience listed, I'm estimating John's hourly rate to be around $75. This is a relatively conservative estimate, considering the demand for business analysts and data analysts in the US job market. According to the Bureau of Labor Statistics, the median annual salary for business analysts is around $80,000, which translates to approximately $38-$40 per hour. However, this doesn't take into account the specific skills and experience John brings to the table. Given his expertise in Microsoft Excel, SQL, and Visual Basic For Applications, I'm rounding down to $75 per hour to reflect his mid-level skills and experience.
