Where can i find Legend of Zelda sheet music for violin and viola?

For Christmas, I want to play my boyfriend a few songs from Legend of Zelda, since he is a big fan. I play violin & his brother plays viola, so I'm going to ask his brother if he would play with me also. I think this would be a pretty awesome gift, and might top the gift I got him last Christmas :P (I got him 3 katanas, 12,24,&32 in. i think) Any help will be useful (:
