String Quartet Sheet Music for Beach Boy's "God Only Knows"   

I need sheet music for "God Only Knows" by the Beach Boys (from "Pet
Sounds," of course) for a STRING QUARTET.

Unfortunately, it needs to be for a string quartet specifically (ie,
not a guitar tab). I don't really know anything about
music, but i will try to contact the quartet in question if anyone
would like clarifications on what does/doesn't qualify.

An internet address where I can order it is preferable, but any music
store that will ship it or whatever is fine. Not sure about an offer
to personally transcribe the sheet music, since I don't really know
what the going rate for such a thing would be.
