depending on which sectors in particular I would recommend one  of the major market research publishers such as Mintel or Key Notes. Alternatively keep an eye out for industry related research in newspapers such as the FT which regularly issue sector related information.

You didn't specify where the local area was.  If you let us know which city, state or country then I'll see what I can find for you.  Most Chamber of Commerce offices have this type of information on their websites (or in a brochure if you go to their office).  This would be the first place I start to look.

This isnt really a software issue as much as it being an information issue.  You should register with some trade organizations that should be able to provide you with the information regarding the estimated size of the industry.  Once you have that all you'll need to do is divide your revenue into that figure and you have your answer.
