Budget estimate

$100,000 – $150,000

The solicitation does not disclose the contract ceiling. Based on typical herbicide application rates (≈ $150‑$200 per acre) for 720 acres, plus labor, travel, insurance, and overhead, a reasonable estimate falls between $100 k and $150 k for the three‑year contract. Factors influencing the range include the cost of labor (prevailing‑wage rates), travel distances, equipment depreciation, and any additional compliance costs.
