If it were me taking care of this baby - I would contact what I think is THE best animal rescue organization/sanctuary in the United States:
Best Friends Animal Society. They take in some of the worst horror stories around - they took in Michael Vick's dogs and rehabilitated them, they take in animals w/ deformities and/or horrendous injuries and bring them to health.
I am SURE they would know of a surgeon or referral for you. And who knows, maybe they would even pay the surgeon directly for Emma's surgery - without you having to surrender Emma. I had PMd you about Best Friends previously, but never heard back. They truly are incredible.
