Newbie Friendly basically mean a provider is willing to take an appointment with a client who is totally new to the Hobby. Yes being newbie friendly does seem to increase business but the down side is Newbies tend to be very nervous and a provider has to be extremely careful when taking a newbie because they will not have reference from other providers.
Hope that answer's your question

I like my life a lot so I rather not bother doing extra work to then be annoyed.

I've found newbies to be perfectly fun!

Newbie friendly, as has been posted, means that someone is willing to see someone who has no reviews and no references. That's fine with me as long as they are willing to provide more personal information for me to verify them.  

I don't know if it brings in more business or not- I haven't thought about it. No problems with newbies- actually the opposite. People who have references often think that it's all they need to provide for me to see them. But I still need more information. And sometimes those with references have issues providing more info. So ultimately, they can be more difficult to screen.
