I Need Music And SFX For My Endless Runner Game

I'm looking for an experienced composer to create epic and dramatic music as well as fantastic sound effects for my endless runner game. The tracks and sounds effects should fit within a fantasy theme, and will be tailored to fit the pace and intensity of the game. In total, I am looking for 1-5 tracks or sound effects. The composer must have a portfolio of proven works or samples that they can share, and be open to feedback throughout the development process. Experience in creating music or sound effects for mobile games is highly preferred. Thanks!
