I'm also looking for MCC/JOC..
I'm 0:30hr away from finishing my CPL, with PTT (ex Multiflight) at Leeds. Like you say, they are not currently carrying out the MCC course anymore.
I am looking at Cardiff Aviation Training, as they appear to be a reputable outfit, offering both the MCC and JOC courses in a full motion 747-400 simulator. Their 36 hour course is around £4'500 (also available is an extra 4 hour sortie for URT, approx £500). I'm hoping to do my MCC/JOC in March.
