I am doing research on computer accessories, right now looking at
computer mice.  I want to find out how many computer mice are sold
worldwide in the past (back 3+ years), today, and expected to be sold
in the future (forward 3+ years).  I need the figures separated by the
different types of mice, as defined by those with the rolling ball and
those with the little red light (optical).  Ideally, the figures would
be for the number of mice sold, but having sales dollars is also
acceptable.

I will need sources for the information cited.  

I will tip very well if all of the information is provided.  Partial
information is acceptable but please ask for clarification.

I need the information by Monday night.  

Thanks and good luck.
