No respectable breeder would let you have a puppy at Christmas, it is far too a hectic time to be concentrating on a new pup and too traumatic for the pup.
Why don't you have a look at the Siberian Husky website
http://www.siberianhuskyclub.com/breeders and contact the secretary, if there are some litters around, it maybe possible to look before Christmas and if you decide to go ahead you could always give your son a photo of the puppy for Christmas and perhaps some new things for the puppy ready for when you do get him/her.
Good Luck
