I understand your confusion here.
I did some research and found that if you click on the above link, it will bring you to a page with the picture and criteria of the property. On the right of the picture, if you scroll down past bedrooms, bathrooms etc., you will see the word Landwatch. Click on that. Then scroll down to the bottom of that page and you will see the name Sullivan. He appears to be the listing agent and you are able to email him there.
Hope that helps you.
