Okay, let’s tackle this. So Dave Du Val has a mix of skills that are valuable in the non-profit and accounting spaces. Tax preparation and accounting are in demand, but the rate for these services can vary widely depending on experience and location. Dave is based in Citrus Heights, California, which is a suburban area with a moderate cost of living. Considering his skills and location, I'd estimate his hourly rate to be on the lower side of the range for tax preparation and accounting services. Let’s look at some benchmarks. According to the Bureau of Labor Statistics, the median annual salary for accountants in California is around $74,000. For tax preparers, it’s around $48,000. Since Dave has a broad range of skills and experience, I'll estimate his hourly rate to be around $75, which is slightly higher than the median salary for accountants but lower than the median salary for tax preparers.
