It only came across to me that you probably wanted to include the sales
scheduled time within the implementation schedule which I've not for
obvious reasons. 

For the scheduled time for a sales can be varies from 1 to 8 months, but
I concur with Lennard Regebro that in normal conditions can go at most
to 5 months. I'm including the slack phase here just because a sales IMO
is done when at least the customer has paid 0.5 of the overall project
cost (product + consulting) and that rarely happens before the project
actually starts.

As a safe guard, inline with Lennard Regebro I'm estimating passed time
not man/work hours.

Nevertheless this is still vague because I'm not including human
resources, location etc, etc. But I believe that I can rely on this at
least as a priori estimate.

I also concur with Lennart on this one. This could most probably result
in a disaster if stages and estimates were done and serialized in this
manner for projects that are more then simple. Nevertheless this is
something that appears quite often in vendor/consultant proposals
irrespective of CM project complexity.
