Female Pit bull puppy

I want to find a good home for my 4-month-old pitbull. She's a young dog and needs to learn some good behavior. I have a baby who is 5 months old and another pitbull to take care of, so I can't give her the attention she needs. I'm asking for $200 or the best offer. Usually, these dogs cost between $500 and $800. She has had her vaccinations and comes with a leash and collar.
