AKG, i am one of the designers for cardboards so can answer this. You can send them your own design, the board price stays the same. You will need to choose which board you want and get the dimensions sent to you for that board, ie 130cm by 39cm for new wake style board. You need to do your design at actual size at 300dpi and send it to them as a flatened .psd file You can contact them via
[email protected] and Dan will answer any further questions you may have.
