I just have to say you area very lucky girl. I saw a thread where another girl was basically detailing her cham's death from an unknown ailment, and she couldn't find a vet. You have a neighbor that works at a reptilian vet. How fortunate can any chameleon keeper be? I sure hope your little girl...
This may be a lesson to many either new Chameleon owners or prospective buyers. I never even thought about whether there are any vets around me that would have any idea what to do. I'm sorry for you and your situation, and even sadder for your chameleon. I hope things change quickly.
