New clutch, TD42T Patrol

Looks like my Patrol's clutch has had it's day. (250,000 klms!)

Any suggestions on how much I should pay to have it done?

Any particular clutch recommended?

Northside Brisbane, anyone have a recommended mechanic to do the job?

Thanks in advance. I've done many replacement clutches on four and six cylinder cars, but this is a bit beyond me these days..... The Patrol gearbox and transfer case would weigh more than most smaller engines I've worked on!
