The short answer
The cost to hire a security guard in Arizona depends on the assignment, so an accurate quote requires more than a requested headcount. The largest factors typically include armed or unarmed staffing, location, shift length, total weekly hours, time of day, short-term versus ongoing service, required experience, supervisory needs, equipment, holidays, and how quickly coverage must begin.
What to know
The work itself also changes the price. A stationary lobby post with defined access-control duties differs from a vehicle patrol covering several properties, an overnight construction site, a healthcare environment, or an event with alcohol and multiple entrances. Specialized training, a patrol vehicle, communications equipment, body-worn equipment, or additional reporting requirements can affect the scope. Contract terms, overtime exposure, relief staffing, and insurance requirements should also be clear.
For a useful comparison, give every security company the same site information and ask for a written scope: post locations, schedule, duties, supervision, reporting, equipment, and exclusions. Do not compare an hourly number without confirming what it includes. Arrow advertises a free on-site security consultation and quote; the resulting proposal should explain the assumptions behind the price and identify any minimum shift, deposit, holiday, cancellation, or emergency-start provisions.
