Good idea, Sixpence.
Brancusi made his own, Moore made his own, Picasso made his own. What what ONE man can do, another can do (-Anthony Hopkins/ The Edge).
Get yourself a hunk of marble, a chisel, and a hammer. Simply chip away anything that doesn't look like a Henry Moore sculpture.
I wouldn't recommend making your own plinth, though. Those should be ordered online from a reputable plinth dealer.
