I would like a list of companies who make software for the following 
vertical markets:  manufacturing, legal, construction, health care.  

The software should be Windows based.

The companies should be looking to or have the appearance of looking
to partner with a technical services company to assist with the
installation/configuration of their software and any necessary
hardware after the sale.

Each company need only sell software for one of the vertical markets. 
If they sell software for more than one, that's fine as well, but
only one is required.
 
I would like at least two companies in each vertical market.

Any emphasis on the Great Lakes area, (particularly Michigan),  is
also
a plus.
