You'll need a good 3d app such as TS as Velen mentioned, or Max, LW, C4d, Maya etc, but what you need the most is a lot of patience, there are folks who take years perfecting a figure, but i'd say you'd be looking at months minimum if your experienced at modeling...if your not experienced i'd say use some poser figures or download others and change them around to suit your use coz starting by building a figure (human or otherwise if your going into detail) could well put you off 3d for life ;o)....Steve
