Requested WoW macro

i would like a macro that will target the nearest enemy, cast lightning bolt once and then cast ghost wolf in one click. i would be using this for farming low level creatures (that can be dropped with a single lightning bolt)for skinning more quickly. i would be binding this to a mouse button and the idea of clicking one mouse button and not only targeting but killing and casting the spell to get to the corpse quickly is really appealing. A macro that targets the nearest corpse, loots, and then skins would also be awesome.
