In addition to "privacy and entertaining space" can we presume that you will also want to enhance the yard/house by improving the appearance and views with plantings? If so, we'd need to see the complete back house face, and the outward looking view (toward the property line) from the most likely patio location, which would be just outside the back door. For the latter, place the camera outside the back door and begin by aiming toward farthest left. While remaining in the same camera position, continue panning/pivoting the camera, taking slightly overlapping shots until you have captured the far right view. The house will show in the first and last picture. To capture the house, move the camera to the property line, in line with the center of the house, looking back at it. Take pictures that begin at the left side property line. Continue panning all the way to the right side property line, with the house in between the starting and finishing point. All of this can probably be dine in about 7 or 8 pictures. Describe exactly where the back lot line is (per something visible in the picture.)

Either an experienced landscape designer or a landscape architect could work here. Ask around for recommendations, have a budget in mind that is reasonable for the work you want done (this doesn't sound like a job with a budget of a couple thousand dollars) and when you start talking with folks, ask for references and to see work they've done previously. Decide if your budget will let all the work happen at once or if you want to do some parts now such as hardscape and groundcover and will need to do the rest of the work in stages. Realize that timing is such that in many parts of the country, everyone is starting to think about work that they want done this season, so at this time of year you may find that professionals are fairly busy. Consider whether you can live with a season of something like mulch or a green cover crop or hydroseeded grass to hold the soil while plans are made by someone you really want to do the work or if you want construction to start this season.

Roughly, what is the dollar figure you don't want to exceed and where do you live?
