HotDave -
I'm afraid I'm out of Celebi at the moment (I'll clone some more tonight if I find the time).
However, I'm free to trade right now so we can trade 2 for 2, or if you find a alternate pokemon I can trade you 3:3 now. If you find an alternative, I'm sure I can find a 4th in your thread later to trade you the celebi tonight or this weekend, or I can just give it to you for being cool. :P
