All four of these ladies are visiting the bay at the same time.  
Anybody have any recommendations/thoughts?  
Anais Vincent
Michelle Amour
Carmen Love
Laila Cruz

Then try back channelling a monger that has seen one or more of the ladies recently. Have you done any research yourself?

I have but it seems this must be some sort of agency because they seem to travel to the same cities at the same time

What does that have to do with it?
