I think the 40 year old (you have to use ages, these 2 change their names so often) and the 21 year old aren't working together anymore.
The 21 year old is the one trying to run the agency, she went on a strange rant on another board about " only girls that are on drugs hide their faces in ads" (even though she hid her face for a long time in ads) She has changed her appearance and put on a fair amount of weight during her short stay in Brandon, i am willing to bet she will move on soon. She seems to be making a final push for business by posting shill ads for herself which usually signals the beginning of the end...
Alex is the girl that advertises $300 and a pretty limited menu (IMO) but reviews seem pretty good. Her rates are equal to most traveling girls and Brandon has become a fairly regular stop for quite a few quality ladies on tour. If the touring ladies stopped coming she would probably be my choice of the 3 (Brandon is a small town and the other 2 seem to have more drama, which is exactly what you don't need in a small town)
