Blue bully (DECATUR)

I have 1.
5 year old female blue bully NO SHE IS NOT papered the person we rescued her from didn’t pay for her rights or papers and I wasn’t planning on breeding so it wasn’t a big deal to me .
She is kind of shy due to her previous situation but a total sweetie good with kids of all ages she potty trained and loves to play once she gets use to her surroundings she had a previous litter of pups (with her abusive owner )(he got her she had pups then he had no use for her ).
I got her out of her situation but unable to keep her full time I have put a lot of work into her but she needs more (she still crouches when someone raises their voice or hand to quickly) she won’t bite or growl but she just lowers her body she needs a home where she will get plenty of love and time .
She has been around kids , other dogs and farm animals and done great there’s also tons of cats around the neighborhood and she don’t try to go after them .
Once again before I get this question She is NOT papered.
Asking a rehome fee of 5@0 obo she also will probably need shots since the only proof he gave me was tractor supply shot packages .
