Animated Emoticon Gif's

I need a set of animated Emoticons for an online chat system. I need around 30 or them and I'm looking for high quality like Skype or YM. I would need to see previous work - you need to prove to me you can do this and if you can't I won't pay. Note: the quality must be extremely high - I'm not looking for a ruff attempt - I can do this myself. Note: they need to be GIF and they need to appear correctly in the major browsers - chrome, IE, FF (I've seen some GIF animations look poor in IE because of animation cycles speeds). thx Adam
