I need a background design to use on business cards

Design details: I have a background design that I would like recreated in high resolution, so that it can be used for marketing materials i.e. business cards.
Ideas for the visual style: see attachment. I would like my design to be almost identical to this in colour and design
Extra notes: This design is for a business card, so I have attached 2 images, one for the front and one for the back of the card. Please could you recreate these 2 images in high res.
