Budget estimate

$350,000 – $460,000

The solicitation caps the total contract price at $461,000. Assuming the contractor can meet the scope efficiently, the expected earnings will be near the ceiling, likely between $350,000 (if some cost allowances are reduced) and $460,000 (full award). Factors influencing the range include the proportion of parts/materials reimbursable (capped at 10 % of that line), labor rates, travel costs, and any applicable small‑business or DVBE preferences that could affect the effective price.
