Escrow domain purchases on NamePros?

I was the high bidder on a domain that was for sale here at NamePros and was just informed that I had the winning bid and to send the money to a paypal account. I don't know the seller and am reluctant to send money to a stranger. Is there an escrow process I can use so that the money is not released until the name is transferred to me. (This is what Afternic and others do when I sell a name)
