I'm also looking for recycled card, but I may be able to help you with die cutting. I work form home but have the equipment to cut various materials including vinyl, card, etc. from vector designs.
I've been contemplating making my own recycled paper / card, but I need to make a mesh somehow...
I know your message is 4 years old, so you might be sorted by now, thought i'd give you a try...you never know.
