You say nothing about their CHIC numbers, their Titles, or their lines. You have two breeders, the dam's and the sire's, whom you should have contacted before allowing this breeding. If you have a litter of a breed that is not common and you have no established breed fanciers interested in them, then you shouldn't have bred the litter.
Drop the price to sell these puppies. Don't allow another breeding until or unless you're willing to do your groundwork: health tests, competition titles, and an education in genetics.
