I think you could try wings. A number of merchants use it and it is free. Go to Wings 3D.com. There are a lot of choices for programs that can do a lot of what you want. Try a few demos and see what you like. Wings and Blender are both free and have a fairly large community so you can ask questions. Silo and AC3D have pretty good support and are relativly low priced.
