4 chihuahua puppies that are about to be 7 weeks old

Hi i already have got 4 chihuahua puppies that are gonna be 7 weeks old and able to automatically get to a new home. My Rehoming fee is 500 for your puppies. In return i have to text back 30 days later to see how the puppies are doing. They're gonna need your attention as puppies and it would be much preferly when they are not with small children when still young.
