I have a product to sell to those who own and run computer firms.  By
computer firms I mean those that help non-tech businesses with their
systems hardware and networking problems.  These could be any where
from one man firms to 20+employee firms.

I need to know if any market research has been done (freely
available?) that shows what these owners read, where do they go for
products, and are any list available, as well as a break down of their
industry (average income, payroll, gross reciepts, etc.)?  I am
especially interested if they have any type of national associations.

I want to advertize to them.  Those few that I have interviewed buy
most of their products and get most of their news on-line.  Blast
emails, even to opt in list are not likely to work, as tech savvy as
these are they usually have superb spam blockers.

So included with the above information I am looking for the best
possible way to get advertizing in front of these people. With out
having a superbowl commercial budget.  You conclusions/opinions will
be welcome.
