Scheduling logistics

Here's a question for the community - when do you reach out to providers to schedule an appt.? I have always waited until I see them putting up an ad and I am ready around the time I start looking or at least later that day (this applies to those who put up ads that day like STG). If they are traveling providers and put up ads in advance, like Tryst, I sometimes book further in advance. I always assumed that if they didn't have an ad up, they wouldn't respond. Of course, this is not the case for those UTR who don't advertise.

There are providers however, that still advertise but don't do so often (eg. Kaylee Marie, Extreme Alexis, etc.).

So do you guys just reach out whenever you want a date? Plan more ahead? Wait 'til they advertise or just reach out anyway? Which method yields the most success? Ladies, what do you prefer?
Depends on the provider and what they want. Some providers will msg you if they are available - something I don't like, because I don't look at that number unless I am looking.

STG providers - msg if they posted that day, or within the past few days if they don't post often - unless they say available between such and such.

Other places? MSG them as soon as you want to schedule. For one of my regular traveling providers I would send them a message a week or more before hand, or they will message me (because we've agreed on that and they know I'll get back to them eventually).
