I have been meeting mostly using reverse bookings (out calls) for a couple of years. It's always a mixed bag, and you need to sift through (or just not get annoyed with the number of time wasters). I tend to find you get a lot of bids in the first few days, then it picks up again in the last week before the meet. I have always had bad experiences if you post one for the following day. My most valuable lesson from it is that if you feel there is anything amiss with the profile, just ignore the bid, and be prepared to save your money for another day if no-one suitable replies.
Best of luck with finding someone who fits the bill.
