Emergency/Exotic Vet in South Jersey area?

I was wondering if anyone knows of a reputable exotic veterinarian that has experience treating chinchillas in the South Jersey area? I live near Cherry Hill, NJ and I have called around to many local vets in my area who state that they treat exotics, however all of them have said that they either have no one on staff or only one doctor who is slightly familiar with treating them. I also would like to find an emergency 24 hour vet who can treat chinchillas as well. All of the emergency vets that I have called said they cannot guarantee that there is always going to be someone working who is familiar with chins. They said to call ahead and see if they can accommodate them if an emergency arises, but honestly in the case of an emergency, the last thing I'd want to do is call around to a bunch of places trying to find someone who can help them. I want to have this all taken care of in advance to get them the quickest treatment possible. I don't mind driving a half hour or so, but I don't necessarily want to be much further away in case of an emergency. Thank you in advance for your help!
