I am looking for a list of software dealers or resellers in California
that specifically focus on the construction industry - ie they sell to
general contractors, electrical contractors, HVAC installation
companies, refridgeration & cooling companies, etc.  I am not
interested in manufacturers of construction software such as
Timberline, Dexter & Chaney, Masterbuilder, etc. but I am looking for
the (often small) companies that resell or service their products or
products similar to theirs.  I have found several so far including
Aquirre Bruce & Collum, Ginazane.com, CBS Software, Cfo-togo.com,
realware, Suitable1.com, Paragon & CIT.
