I think you can find them on the service section but many escrows are accepting bitcoin as their only payment in my knowledge,so you can contact them pesonally about accepting the other coins as their payment.
*Edit:I just found the Escrow serivces available on this thread here :
https://bitcointalk.org/index.php?topic=276897.0 .Most of them are accepting ETH also,I hope this will help you.
