Hello, M.oonestone,
I moved your topic into the Playing Card Plethora. You're no longer merely in the D&D phase - you're running a Kickstarter and you're adequately funded to print, so welcome to the PCP.
You mentioned on your KS page that you two used to try cardistry but found your small hands inadequate to the task. Have you considered trying it with bridge-sized decks? They're a quarter-inch more narrow than poker-sized cards - I know of many people with smaller hands who use them, and ironically, they've become the standard for many casino poker tables (the smaller size makes it easier to conceal them when peeking at the indices).
Your project does look interesting, but maybe you should have considered a stretch goal for an upgrade on the printer. I've only seen a little of PrintNinja's playing card work, and frankly, I wasn't very impressed. Companies like Expert PCC or Legends PCC would have been within your price range, I suspect, depending on how you budgeted your project. People around here take their printers very seriously.
