£840 is bloody shocking, greasing the fork pivot will only temporarily solve it.
best option is
all from a mk2 clio clutch fork
plate that bolts through clutch cable hole on gearbox
plastic pivot cap from behind the fork(slightly bigger than the ones fitted to jb3 and jc5 boxes)
clutch release bearing
get them from a scrappie or the stealers, it will make the clutch a load better! not as heavy.
shame you live so far away i would have done it for you for a few beer tokens
