This is a mini-rant. If you don't agree take it with a grain of salt.
Several ladies posted ads today, I would have to have like to inquire about their services. But with only 24-48 hours lead time it is difficult for me to adjust my schedule, to attempt to see them.
I would say that if you are going to be in town for the weekend post with more lead time. I am not sure if there is a cap on ad postings but there should be a way to have them put up an ad earlier and then put a second ad up when it is closer to their advertised arrival.
Just my 2 cents
