Giftcard module for prestashop

hi! I need a giftcard module. the basic idea is when someone goes to a product page, he can buy it or instead he can buy a giftcard. So in the backend there will be a giftcard tracking system. It cannot be done with the current vouchar system of prestashop. pm me for details. **Can increase my budget if you have better ideas. So feel free to bid. I am not looking for the cheapest. **payment through escrow only.
