Labor costs

I have a 1995 bmw 525i, with 160k miles, 2.5L i-6. I have suspension work that needs to be done. I need shocks/struts all around, swaybar links replaced, and an allignment.

I have been given an estimate between $1800-2000. I think this is a bit high. I think I can get the job done for $300-500 less, as the repair-person contacted a bmw dealer for parts.

my question is not what the total cost should be, but how many labor hours this job should take. I find the internet is infinately useful to find parts costs, but I can't find any estimated repair times. If I can find these times, then I can figure if my price is fair or not.
