Where can I find a sewing pattern bag (online or retail)?

I am looking for a sewing pattern for this style Sling Bag illustrated in the following link: http://esiamcenter.com/shop/images/large/bags/bag74_LRG.jpg If you know exactly where this trend is whether online or retail (let me know the name of the pattern maker), I would be very grateful. Thank you so much! *** Please do not say, try to "Walmart", "Michaels" or Joann fabrics. I do not need generic responses .. Please be specific .*****
