The only one on this list I would pay to have done is the cabin filter. I did one myself on a C-Class Mercedes and it was about the same level of difficulty. Between the bad lighting and all the twisting and turning due to the awkward angles, I about wore out the F word.
I have replaced entire exhaust systems with less frustration.
I will happily pay someone $50 to $100 every 2-3 years to handle this for me.
