It depends on when you want/need to see the lady.
Example - I sent out a PM to a provider recently, saying I was traveling, would be in her town the next day, could we schedule?
I got an incredibly prompt and pleasant response to my PM - within minutes.
The provider needed some info - I PM'ed her back.
She never opened the second PM.
Same sorta deal with another lady - only via email.
On the plus side - I was done with traveling, and I scheduled with an incredibly patient lady where we had both been juggling scheduling conflicts. We worked them out, and were able to schedule a session. We both worked together to make it happen, drama-free(review pending; I haven't had time to sit down and compose it yet).
So, it's a crapshoot.
Long story short - if yer willing to wait and yer schedule's flexible, who knows? It might work out. Or you might just be waiting.
