Well given such constraints, your most accurate estimates are likely to come
from an astrologer - or even an economist - nah! thats going a bit far. Ill
stick with the astrologer.

Failing that you could do what I do when subjected to the gnashing of teeth
routine.
These estimates arent worth [one of Mark's this's] but the proportions are
correct - just not the magnitude:

First you estimate the times using the method you think would actually come
up with something thats relatively accurate. This will of course give you
estimates that the client won't accept.

The client of course already has their own 'estimate' (they call it a
deadline). You see how many hours there are until that deadline, and then
allocate your estimates to add up to that based on the proportions in the
'real' estimate.

Then think of something that sounds quite unlikely to occur (but is in fact
100% certain (an unexpected windows bug perhaps?)) and make a small note on
the quote that if this happens it just might possibily in the worst case
increase the estimates by a factor of x (where of course x is the value that
the clients estimate of total work needs to be multiplied with to get the
real estimate of total work...)

These have all been good suggestions, but I am constrained here by a number
of factors.

All our estimates have to be in hours.
There is screaming and wailing and gnashing of teeth if the estimate is "too
big".
We are not a software house, so the business gets to set schedules.
We are a HIGHLY seasonal business, this forces many scheduling decisions.
etc. etc.

Thanks to everyone.

Simon
