WELCOME!!!
Please don't buy from a pet store - they are the reason puppy mills excist.
Ask your local Vet - they may know of someone.
It took me almost a year to find mine and althought I did rescue one from a pet store (he had been there over 6 months, he had not had shots since he was 9 weeks old, had fleas, tape worms, underweight, and will need knee surgery due to over breeding of his mother) - I love him to death and would sell my house to care for him - but we have to all do what we can to stop puppy mills.

Good Luck and hang in there it will be worth the wait.
