I am sorry that you are having to rehome your baby girl.
You asked for a reasonable price for her and I would say between $300 to 500 to a good home that would love and take care of her.
It is often mentioned here that if you give a dog away for free, the adopter may not appreciate the dog and also may not be able to pay the vet and care fees.
Good luck, and make sure you visit and screen the new mom/ dad and check that they have the means to care for your baby. Please find a home in your area so you can check it out well.
By the way, if she is not fixed, that should be a condition of sale if you are not able to do it. Otherwise she may be used to breed!! You don't want that to happen.
