Composer for 3-hour crime drama

We're at the final stages of post-production (dialogue/foley mix and colour grade almost locked in), and now looking for a composer who can compose/arrange/produce the music for the 3-parts (3 hours total runtime). This is a British crime drama, and we're after a theme to run throughout the show, which also uses the same blueprint as many other crime dramas. We'd essentially like to put our own stamp on this, but without being too "out of the box" that it becomes distracting.
