These are all great. However, be sure to calculate an estimated amount of square footage that is taken up by plant material. Based on square footage alone may have you over estimating your mulch which will over estimate your time to spread and thus raise your price higher than it needs to be.
I am not saying that you don't want to get as much as possible out of the job, get what the market will bear. I am only suggesting to keep in mind that even though you may have 2,000 square feet of beds, maybe only 1200 square feet require mulch due to plant material taken up the rest of the area.
