How much should I ask for my puppies?

My dog is due Aug. 8 to have puppies. I'm not a breeder nor did I want this pregnancy but I am treating it as if it was. The pups will be at least 8 wks old, have at least there first shots, have there dew claws removed, come with a care kit and have an unconditional guarantee, meaning if it gets sick or dies due to something genetic or whatnot or if they no longer can keep it I will take it back. Now I know there justs mutts and I don't want a fortune for them, just to see they go to good homes. The pups will be 50% Labrador Retriever, 1/4 Chow Chow and 1/4 Beagle not that it matters. So am I missing anything? What should I ask for them? And please I know to have my b*tch spayed but due to somethings out of my control shes like this. Thanks.
