@Bobbi14, there is no "admin" who needs to put your listing on the site. Your listing appeared on the site the moment you made it active. The reason no one is finding your listing is because of the restrictions you put on it.
I don't think you are fully appreciating what @Clare0 is communicating to you.
The only people who will see your listing are people who say they want to vacation in Green Valley, AZ from exactly Jan 1 to April 1.
If they say they want to vacation from Jan 1 to Mar 15, they won't see your listing.
If they say they want to vacation from Dec 29 to Apr 1, they won't see your listing.
If they say they want to vacation from Jan 1 to Apr 2, they won't see your listing.
Essentially, I would predict that exactly zero people would see your listing as it is currently set up. Adding a few days at the beginning or end won't make it much better.
Think about it: 3 experienced AirBnB hosts were told exactly where your listing was and could not find it.
@Clare0 eventually found it because she is an AirBnB ninja, and also went through a fair amount of trouble.
I understand you want to rent your listing for only 90 days; that's fine. But you have to set up your listing so that people can find it. Then, once they find your listing, you can talk to them about their travel plans.
But if no one can find your listing, you will have no one to talk to.
Just to be completely clear: If you don't remove the 90-day minimum, no one will see your listing.
