I usually drop an Adultwork Pro$$ie an email initially. If I get a decent and positive response I'll book, if not I move on. To my mind a one liner, for example "call me hun xx", when I've asked something specific (there is always something) is a not so good indicator and a bad sign. I will always speak to the girl before leaving for any Punt and have at least the postcode before setting off. This works for me and I'm usually happy with the outcome. If a girl can be bothered to take time to deal with a bit of correspondence she is more likely to be bothered full stop IMO.
It of course depends on when she's working or logs in so a bit of advance planning may be best though it's worked fine for same day as well.
As for the initial question, maybe as the same names sometimes crop up in the Feedback for those I see. On that, it is sometimes worth going through Punters feedback as you might find another Pro$$ie that might take your fancy.
