Create an Animation

I need a 3d model of an "authoritative" but still somewhat funny character. Looking maybe something like the Monopoly guy, but not the same, that's just a clue. Shouldn't be (too) old, but should be mature enough to be convincing. I need three different animations of him. The assumption is that the user had asked "Should I do it?" (whatever dilemma he has). Then the guy is supposed to respond, so every animation starts with the guy thinking for a second. Then the animation continues with him saying one of the following in convincing tone: - Yes! You can do it! Do it! - No! I say you don't do it. I forbid! - I'm just not sure. Sorry, I'm busy now. I need the guy and the animations that display him saying the things above. I need facial expressions to follow the content of the sentences. I actually need an animation fit for using in iPhone applications, so the format must not be inapplicable for that. I don't need the voice, just animations, I'll provide the voice. The style should be simplistic, (iPhone simplistic), and not too complex.
