Basically you need a producer to arrange the whole tune from the scratch... I am a producer composer for more than 15 years, I realised music for TV, but I don't make demos for free... if you want to listen to one of my tunes in "epic style", I'll send you a private link.
p.s. I posted my fee, but if you want "real" musicians playing strings or horns, there will be an additional fee to pay the musicians.
