Sendean will probably do it, although prepare for your wallet to be emptied by them.
But don't bother. There is Brian Mickleboro, and he deserves the business - a competent repairman and a very friendly guy on the phone as well, and there are others on this fora who can vouch for him. Just package your camera well, ensure you pick sufficient compensation level for your camera and send it by Special Delivery.
