Budget estimate

$500,000 – $2,000,000

Based on the scope of work and the requirements for the Independent Cost Estimator, the estimated budget for this contract could range from $500,000 to $2,000,000 over the five-year contract term. This estimate is based on the assumption that the ICE will work on average 20 hours per week at an hourly rate of $100-$200 per hour, and will also include overhead and profit. The actual budget will depend on the specific services provided, the number of hours worked, and the rates negotiated with the contractor.
