Song composition for sci fi project

I'm looking for an epic song to embody my science fiction (space opera) project (dmokrevival.com). I'm looking for a digital production file, and the sheet music, for a score that's similar to the revamped 2013 star trek theme, 2004 battlestar galactica colonial anthem, or the theme from Inception the movie. I'm looking to have the three main races represented in the theme by use of: french horn (epic ancient), violin (youthful, energetic), and sarangi or deep baritone saxophone (darker, intense). Based on portfolio and experience, price can be negotiated.
