Hi Shandon,
I totally love the concept you have going on here. Very nice!
This is kind of "out there," but thought I would bring this up: The history of the meaning behind the the ace of spades in some circles is that it is considered the death card, an ending, or other sinister meaning, etc., and therefore projects a negative connotation, so it might not be the best to use for a business. (I know, I'm weird.

)
Also, might a red card - ace of hearts or diamonds - stand out more?
I do love your card idea, though, and your design. Very innovative and imaginative!
