want to help my animal pet surgery

l am humbly knocking to the hearts of all pet lovers out here. my fur baby wisdom, will be undergoing a leg or hand amputation anytime soon. It has started out as an open wound. That she got few weeks ago that we tried to cure but never got healed untill it got worse and finally ended up to amputation of her right or left hand pains me to see her suffer more and so my mom consented to have The opertation before it further spreads Through out her whole system which may cause her death. the surgery would cost a sot, roughly around 30K and we'res still trying to putch for a lower charge. (30K for the surgery plus other fees such as consultion, lab, doctor fees etc). l really want to slove my dearst wisdom and any dontion, would help for surgery.
