Other options that are not books have been mentioned here before many times. But Lulu is a place to create books, so other options have never been taken up. Very possibly because the POD machines Lulu's printers use can only create books.
All I can suggest is you do the book here and have them delivered to yourself, and have the cards made elsewhere. You then advertise the set and fill the orders.
Another option is to create the book with the card images on the pages, to be cut out and glued to card. But colour printing is not cheap, and every page will be classed as being colour.
The durability demands on the card they stick them on to, and the glue they use. The paper Lulu use is smooth pristine white, so is good for images.
The actual book covers are as thick as many cards. I once reproduced two types of Numerology charts on the back of one, but the space is a bit limited for a pack of cards!
One other alternative is to have them on the pages (single sided) as I previously suggested, and they could photocopy them and take the copies to a local printer to print on to card and sliced.
