Mr. Freak (is that how one should address you?!),

Here you go:
Edmund Optics filter list (http://www.edmundoptics.com/onlinecatalog/displayproduct.cfm?productID=1924&sort=description&order=DESC&accsort=&accOrder=ASC&StartRow=21&PageNum=2)
Schott BG-39 2" square filter, 3mm thick, in stock, for $56.
And its transmission curve (http://www.edmundoptics.com/techsupport/resource_center/product_docs/curv_48642.pdf).

Is that large enough? You could mount it in a Cokin type holder.

www.howardglassco.thomasnet.com will cut filters to size, and is cheaper. Jason there delivers exceptional service.
