I'd end the conversation after I heard $275. I wouldn't even think of paying this kind of $$ to any T no matter how good they are. This would be just one reason alone for me to forget about this T.

Even if she didn't charge the outrageous fees, I wouldn't consider seeing anyone who doesn't sound like they are interested in getting new clients. She certainly didn't sound interested on the phone and the fact that she doesn't have any publicly available contact information suggests that she is either not interested in getting clients or she is a weirdo, who is not in touch with reality and who lives in her own world. Either case is a good reason to dismiss her.
