Landscape is a task best left to professionals.  They will make the job much easier due to having all the right equipment.  Most of us don’t own a dump truck of a tractor.  If you do then by all means tackle that do it yourself project.  If you are like most people you have a shovel and wheel barrel.  There is nothing but work awaiting the poor soul that takes on the bear with a switch.  If you still insist on proceeding o  your own then get ready for blisters and callouses. I ended up in the doctors office after one project due to infected blisters.  Believe me, we should have hired help. Brandon Hopkins would have hired it out.
