Oh, my...
I'd advise against it. Seriously. Based solely on the art you've presented here, you're more likely to fail than succeed.
Zombies as a deck theme are TIRED. USPC has done TWO zombie decks of their own, never mind the countless ones they've printed for others.
If you are going to approach the zombie genre as a deck theme, you need to be either different (in a good way, not simply different for the sake of being different) or better than what came before. The art you're presenting here tells me this deck is neither. It has different art styles between the backs and the courts! The courts are somewhat more realistic while the backs are cartoonish. The dividing line between the courts was very popular back in 19th century Europe - not so much since, though, especially on this side of the "pond."
There's been some really great zombie decks out there (and lots of crappy ones, too), and there's nothing to make this deck stand out from the crowd at all. You would need either the most rocking, ass-kicking artwork put to playing card paper or you'd need some other kind of hook or gimmick to make this deck work - or you could go with a cheapo printer and set your goal so low, it's nearly impossible to fail, in which case, why bother, because your profit margin divided by the time put into it would probably not even reach minimum wage for tipped employees, never mind a decent return on your investment. You'd be better off working at a diner during the slowest shift.
I looked at the artist's website you linked to. He's capable of much better than this.
