Anyone willing to create a custom cover for a custom game?

I picked up a physical copy of a brand new MLP-themed Final Fantasy hack NES game at BronyCon this past weekend, but because it's brand new game for a relatively niche audience, there's no typical NES box art (just a promo poster), and I have zero Photoshop skills.  Is there anyone willing to make a UGC cover for me?  Here's the promo poster.

I know it's a lot of work to ask, so I'm willing to pay an art commission fee if anyone's willing to do it.  Thanks an advance, guys.
