Sorry to hear that they do have a different parent company now so it may not be the same. Though I would try calling and talking to someone. Again my experience is 10 years old but the person I talked to on the phone was very accommodating.
Also do you have a local shelter? Give them a call they always know if there is a low cost vet in the area. 2 grand for a sedation and wound cleaning seems really high. Even with antibiotics.
