Thanks for the info, had my eye on her too...but hadn't been able to track down any reviews anywhere. A deposit wouldn't be a deal-breaker for me if she was able to establish that she's a legitimate provider with multiple recent and positive reviews...but that's me.
Not all providers who ask for a deposit are scams, but it's definitely a RED FLAG... especially for a first meeting.
Back in my younger and dumber days, I did go along with "some" deposits if they were reasonable. Then I stopped the first time I got burned. You learn QUICK. XD
