I need a song transposed for multiple intruments. How should I do it?

Okay, so I wanna take the song "equinox" by skrillex, and make sheet music for the following instruments for the song: flute, trumpet, alto saxophone, clarinet, bass clarinet, and piano. Can anyone do that for me, or tell me how to? I only play the trumpet, so I hope you can understand my confusion. Please help :D
