WHAT SHOULD I CHARGE FOR MY PUPIES?

I have a litter of pomeranian pups.....2 males cream and wolf sable....I work with a breeder...she sells her puppies for $400-$700. My puppies are CKC reg...both parents are AKC AND CKC reg and the dad is from champion bloodlines. ( my poms AKc is limited so I couldn't reg them AKC). I wanted to raise one litter of poms.....I was hopping to have a baby girl to keep but since i only got 2 boys i have to sell them b/c if not I will have to have my female fixed....she is inside only and I don't have to have her fixed as long as i have just her.....I was going to ask $500 for my puppies...they will come with their reg, shots, vet care, health garantee from the vet and puppy packs and will start on pad training b4 they leave........what should I charge? IS $500 too much?
