Patios, Walks and Steps

We would like to remove the current steps connecting the 2 levels of our back steps and have an outdoor wood and gravel staircase (like this design https://www.hgtv.com/outdoors/landscaping-and-hardscaping/driveways-and-pathways/how-to-build-a-wood-and-gravel-outdoor-staircase) built and installed instead. We may also want the wooden steps from our back door to the driveway replaced while someone’s coming out.
