WTT: Canon 24-70 2.8L for 70-200

[bango707]

Im looking to trade my two month old Canon 24-70 2.8L for either a Canon 70-200 4L IS or a Canon 70-200 2.8L non IS. If anyone is interested in such a trade please let me know.
My lens is mint, only used on a few occasions.
I want to get a portrait lens instead which is why I am looking to trade.
