Congrats to you! Lethe know you are just starting out and things are not set up exactly the way you would like and would love to meet her. Get your house as ready as possible and when she comes in be confident on what you are selling.
let her know what your plans are. She should understand that you have to advertise a bit early if you are starting soon. Be confident and up front and it should all workout if you are what she is looking for. Good luck!
