Budget estimate

$300,000 – $3,000,000

Based on the information provided, it's difficult to estimate the exact budget for this opportunity. However, considering the scope of the project, which includes auditing the County's financial reports and single audit for three years, with an option to renew for two additional years, the budget could be substantial. The cost of such services can vary widely depending on factors such as the size and complexity of the County's financial operations, the level of expertise required, and the location. A rough estimate for a similar project could be in the range of $100,000 to $500,000 per year, depending on the scope and complexity of the work. Therefore, the total budget for the three-year contract could be in the range of $300,000 to $1,500,000, with the option to renew for two additional years potentially increasing the total budget to $600,000 to $3,000,000.
