The Dragons Gate Campaign might work well for you. Our sessions are almost entirely stand alone sessions (one-shots) but they happen within the context of a living world with many other adventures happening around you. We're a persistent world Pathfinder group currently in beta with six GMs and roughly thirty player characters in the world. We've had at least one game every day for the past few weeks and quite a few of those have been during the UK evening. We're just about to push for our last batch of pre-launch players so its a good time to join us.
