I'm a relative newbie, a couple of encounters over the past six months, so I don't have a lot of references to give for providers.  I am also nervous about giving out a lot of info in an initial contact with a provider.  I am a professional business owner and would be glad to give information after an initial contact via email or text.  I'm also a little nervous calling providers since I don't yet have a hobby phone.  

I just got a rather short response from a well reviewed provider when I asked if she had any availability later in the day and if so, I would call her with any additional information she would need.  Her response was basically "if you don't put your name in the initial contact and send references, I am not going to correspond with or schedule a meeting with you if I have not seen you before".  I felt like I was getting a dressing down for violating an unwritten rule.  I understand the need for protecting yourself if you are a provider and don't really have a problem with any of this, but is it really expected to give your full name to a provider you don't know when all you are trying to do is see if she is available at a later time?  I don't want to insult anyone, but I also don't want to give out that much info to a provider I don't know and may not ever even see.

Any guidance on protocol for initial contact with a provider would be greatly appreciated.
