End of year business greeting card

So we need a card to send at the end of year to our VIP clients. It should be: -Folded card -15 x 21 cm landscape prefered. It's like you take A4 and fold it in half and that's what the card should be OUTSIDE of the card: -Colors: please, see the attached file of our powerpoint presentation style. The colors should be like those -Theme: wavy (like our ppt, calm, peaceful, light and bright at the same time). No real preference just yet for any specific image, so open to suggestions. But an idea could be to put some funky christmas tree, but it should be very professional, not childish! -Logo of the company on the cover page is important and at the back of the card at the bottom as well. INSIDE of the card: -Message inside the card in 4 languages (english, french, arab and chinese. Text should be seperated by the wavy thing (not the text) of our logo. The message should be the following: we thank you for your loyalty and we wish you good end of 2012 and a great start to 2013! -the inside top part should be white and top should have pour logo where employees will be able to sign their names.
