you dont want carrara for modeling. It does have a modeler, but it is not as capable as other tools.

The list is short if you want to model clothing and paint on them.

Luxology Modo, Expensive, long learning curve

Silo, Cheap, sounds good

Hexagon, Cheap i use it

Id start with hexagon, it is pretty straight forward, and has real time displacement painting and texture map painting.

Good luck!
