We start from one fact about your trade: the work looks better every year, and few sites ever show it.
Most trades photograph a job on the last day, because that is when it looks best. Yours is the one trade where the last day is the low point. Fresh mulch, small plants and bare soil between them. Three summers later the same bed is full, and few firms go back to take that picture.
So we build the site around time. Each project page holds the same view at install, after the first season and a year or more later. A winter shot shows the bones of the design. Plant lists name the zone you planted for, and maintenance is the reason the later photos look the way they do.
We also split your two buyers. Someone planning a new backyard wants ideas and a design consult. A property manager wants a steady crew on a schedule. Each one gets a path of its own.
