I agree with the above post. It sounds like a backyard breeder, breeding for profit obviously not for love of the breed... because there really isn't a breed.
On topic, if you still decide to get this puppy, 8 weeks is totally reasonable.
Although beware, toy/miniature dogs are much harder to housetrain than larger breeds, especially if your not around much.
As the others mentioned though, if you want a pup, there are plenty of mixes at your local shelter I bet!
