I charge £400 in labour for the job. Plus whatever parts you want fitted. I'm more expensive that some but I spend two full days doing it.
I also recommend changing the engine seals whilst in there. And I won't fit Chinese parts and dodgy seals.
There are ways to short-cut a clutch job and do it in half the time (and half the labour) that I do it in.
But I won't do it unless I do it my way (Which is the way BMW say to do it).. I'll remove your final drive, shaft and swingarm. I thoroughly check, clean and re-grease everything properly re-torque and align everything as it goes back together. And 8/10 times I find things that need attention that would be missed with the short cuts. Another reason I don't like the other method is that It can rag on loom connections, stretch wires and can break things if you're not really careful and know exactly what you're doing.
I'm not saying it's wrong. It's just not the way BMW would want you to do it (They're not always right though). It's more that it's not the the way I like doing things. But usually people just want the fastest and cheapest method. And they're generally not people I like working for.
FYI. When I was still working for a BMW Main dealer a couple of years ago, a clutch job would usually be about £1200 all in for an 1150 or a 1200 Hexhead.
I payed £1200 to an independent.charged me for fitting parts loosely then charged again for torquing them up rather than torque them when fitting .plus various other charges .on top of a gearbox rebuild by mikeyboy..
