Medieval Fantasy Pixel Art

I am looking for a steam capsule artist who can work in a pixel art style.

My game is a gritty pixel-art tower defence game, I want appropriate capsule art to be made that depicts a grand battle scene where the allied defending units are onlooking a hoarde of enemies approaching them. The sides should be occupied by the game's towers firing down upon the hoarde of enemies. The top center of the screen should house the games logo (also to be designed and created in a pixel art style).
