Budget estimate

$2,000,000 – $5,000,000

The solicitation does not disclose a contract value, but multi‑year audit contracts for a California county of this size typically range from $2 million to $5 million total over the five‑year base period, depending on the breadth of agencies covered and the level of staff deployed. A modest estimate would place the award in the lower‑end of that band, while a more expansive scope (including all listed entities and extensive single‑audit work) could push the total toward $5 million.
