Want to buy double deck card holders

[Mr Rules Twist]

Hopefully this is ok to post here, but if not please let me know. I'm launching a new double deck card game on Kickstarter on Feb 1st. The cards come in a tuckbox, but I would like to offer a nice double deck inexpensive box or leather-type carrying case as a stretch goal. Would need to include my logo on it. Price point would need to be around $5/unit. Anyone have any ideas where I could find something like this?
Thanks!
