Steve,

>From my experience, without getting much into detail, your figure seems
a bit low.  If I was in your position I would quote about 50% above your
fugures.  I'm sure as you already know, your timing is measured when
everything is in place and a rework person is in unison with the work.
However, you must also add the time that it takes to unpack the board and
send it out to the manufacturing floor for rework(i.e.  out of the box,
bags, audit, generation of paperwork, putting boards onto racks).  Also,
more jumper wires you have, more complicated it becomes.  If a sample
board is not provided, someone will need to build a sample board so that
the rework personnel will have a visual reference to work with.  There's
also a matter of learning curve.  If a rework person has to look at a
sample board or the rework instructions after each jumper wire, it takes
quite a bit of time compare to someone that has done this several hundred
times and does not need to refer to documentations to move to the next
jump.  There's also time for cleaning and there's additional time needed
for inspection, not to mention repacking and delivery.
