I live in Coolidge, AZ., we own a Landscaping business and we just opened a nursery about a month ago, and I’m afraid that we(mostly my husband), are over watering, how much water, for example would a Cottonwood Tree(15 gallon pot) need?

This can be hard to judge, as there are many factors that would affect the daily watering. One days where it remains humid or moist, you can water them less. It is always best to inspect each plant to know whether or not it needs water. Most plants will want the top inch of soil to dry out pretty well between waterings.
