Help arranging a rock song

Hi, my band plays rock music. The formula we use is pop rock intros that build into full blown metal. I want to put a different perspective on the music, and would like to know if you would like to help us arrange a pop rock/ metal song. Many thanks.

Additional info:
The song has less than 10 tracks recorded that need mixing. The tracks are cleaned, tuned, and and the song is ready to be mixed. I don't need the song mastered.
