Land Owner Contact Letter & Ground Lease

I am looking for a Land Owner Contact Letter that you have had a good response from and has worked well for you. I am also looking for a good ground lease sample. I am not sure what billboard companies like and don’t like to be in the agreement if I sell it to them. If someone could help me with these items I would greatly appreciate it. You can send them to my email at jthomps730@gmail.com.

Thank you
