Nightwish or Within Temptation orchestra ensemble sheet music arrangements, please?

I don't care if it's free or if I have to buy it, but I am looking for violin, viola, cello, and string b accompanying pieces for any Nightwish or Within Temptation music. There are several songs I enjoy from both bands, so it doesn't matter to me which song I get from them. I need all four parts (maybe even a second violin part as well) to present to my conductor as he has agreed to allow us to play the music if I can supply it. So, any help in my search would be eternally welcome. (And please don't give me links to piano or guitar music sites... all I want is orchestral quartets/quintets. Thank you.)
