Looney pilot
Have you thought about the ATP academy in Southampton. I know it's not exactly what you seem to be looking for, but the place offers MCC and JOC courses. BA, Easy Jet and various other airlines use the academy for cadet and direct entry pilots. It is aimed at recent 509 graduates with the typical 200 hours, but without the necessary multi-crew or jet experience. The school offer a form of sponsored training (not too sure about the details), whereby if selected all or partial training will be paid for and you'll be kept on their books - they seem to have good contacts with Easy, Britannia etc.
I know some of the self-sponsored who have finished from Oxford have taken this route, and it seems that airlines are looking for MCC/JOC rather than just more hours.
Whatever you decide best of luck.
