Have you Seen Gordon Homes, I need your advice?

So I have met Rob Gordon a couple of times. He is a great developer that seemed to get way over our head like many of us. Well he started this project called Azura located in Boca Raton, and now his phone numbers are disconnected, and I have a buyer who even though only a couple people. live there they want to purchase there. I can't get ahold of anyone to tell me how I can show the homes as the only one who has homes listed is you guessed it Rob Gordon. Anyone have any suggestions.
