Welcom Jim/Woogie Man.
Dear OP Jim has a fair amount of breeding experience and his advice is always clearly put.. I do hope you contact him.
It is very hard to know what you know and quite literally books are written about whelping and raising a litter of puppies.
:
Your mamas health is of prime importance : feed frequently, add a calcium supplement - get her calcium levels checked right now is not too soon, and then ask your vet the amount of calcium you should be giving her daily. Often a scrambled egg contains enough calcium with a normal sized litter, how-ever we don't know the weight of your female, and it is best to find out what her calcium levels are. Then start your supplementation.
Puppies should be weighed daily and you should have a means of identifying which pup is which.
Your room should be at about 85 degrees - pups this young can't regulate their body temperature, draft free environment. I would have a cot in the whelping room, to make sure pups are kept warm all night.
You should know how and when to stimulate your puppies development; Dr Carmen Battaglia has some wonderfull free articles, just go to their website.
When you are at the vet have him show you how to tube feed. Better to learn it now, then trying to learn it in the middle of the night.
Again here is another good website :
Volhard Dog Training and Nutrition: Behavior and Training: Behavior
If you don't have your vet on speed dial, assign #1 to him, also gps your nearest emergency ER.
Good luck with your litter!
In terms of pricing; varies too much across the country, I have no idea if the parents are champions, have had all the pre screening breed specific tests, what their conformation is like and their temperament etc.
Given that you are a first time breeder who likely did not have a waiting list, you may end up having to give away the puppies to suitable homes. Also of course you should have prepared a puppy questionnaire for potential buyers to fill out, this is your first screening tool. Buyers will want to know what kind of health guarantee you are offering, and what your contract looks like.
You shall a busy few months indeed.
