I'm looking to even own one of these figures loose myself, so I can't help you much there, but have you thought about seeing what you can get on eBay? Might be pricey but hopefully you could find something that would arrive quickly enough? You could maybe even work something out with a seller to have it sent by express mail or something if you send extra shipping money to them; I haven't tried this but I imagine it might work if no one here can get you one.
Hope that helps, sorry :/
