I highly, HIGHLY, recommend Sportsk.com for jersey customization. They use the same materials as the pros, so it's going to be an authentic customization job, and their prices can't be beat ($47 for a Wings jersey!!). I'm going to send them my blank Winter Classic jersey to customize, once I make up my mind as to who I want on it (Franzen, Lidstrom, Datsyuk or Zetterberg).
SportsK comes highly recommended by not only me, but easily two dozen other LGW members. They have fantastic customer service, prices that cannot be beat ($245 for a customized EDGE Authentic jersey! And yes, it's the genuine article, not one of the cheap Chinese knockoffs) and lightning fast shipping. They are, literally, the only place I will ever buy Red Wings jerseys from.
