CDPHE states that there are no federal, state or local regulatory limits for mold in the home or workplace, that it does not regulate mold, and that the inspection and remediation industries remain completely unregulated.
Where Colorado does impose duties is on landlords rather than contractors. Under the residential habitability legislation a landlord must act within 96 hours of written notice to contain the mold, stop the active water source and install HEPA filtration. That is a tenant's remedy, not a contractor credential.

Colorado issues no credential of its own, so the contractor's certification is doing all the work. Ask which body certified the crew and to what standard, and expect IICRC S520 for mold or S500 for water. Then ask for proof of liability cover, because in Colorado nothing else is being checked on your behalf.
With no state credential to pay for, Colorado pricing tracks the national ranges closely. That cuts both ways, because the cheapest quote and the most careful crew are indistinguishable on paper here.
Drying itself is priced the same in Colorado as anywhere else; the published national ranges are on the pricing page.
Metro guides for Colorado publish once three local facts can be sourced for a city: named operators, local flood risk and the county permit office. Until then the Colorado position above is the state-level answer, and the national guides below cover cost and process.
Colorado does not regulate mold at all: CDPHE says the inspection and remediation industries are completely unregulated.
