Only option at that time is Back pages or whatever the Craigs list alternative you favor is. Though the majority of girls working late tend to have some issue with them. Most normal girls will not work past 10 for their last appointment as that's when drunks start calling. Girls I have seen off the net who work late will agree to a late session but they may have been sleeping so they are usually lazy in the session and not dressed up much when you do arrive.
