Yep it cost a lot. I think it takes about 12 to 15 hours. at $120 an hour plus $700 for parts that is real money.
There are two repair manuals, BMW on disc, you can find that on the internet for free. I forget get the name of the other one.
I think there are some how-to replace the clutch on the web some where.
It is a lot of work and some of the BMW instructions are missleading.
The BMW service manaul is made for mechanics that know what they are doing. Not for the novice. So you made need to find the How to on the web.
I found the job enjoyable, I had to make a couple of the special tools.
You may find the main culprit of the slipping clutch to be the O ring that will get hard and leak engine oil into the clutch housing. No matter you will want to install a new O ring and main seal while it is apart.
Good luck and becarefull
