@Maggie65 It sounds like you need a lot of help/information. Perhaps you should start by reading pretty much *everything* in AirBnB's own Help system. Preferably before you set your listing to go "live".
No one at AirBnB is going to contact you just because you're a new host. You need to do the homework, educate yourself, and then start asking specific questions about things that aren't already available from the Help system.
Being a new host can be confusing and scary. But there are very obvious ways to bring yourself up to speed.
