I would like to compile a list of all the tradeshows taking place in
the US during 2004.  With this list of tradeshows, I would like to
then identify the exhibitors at each. I am especially interested in
exhibitors that are software companies or technology companies.  So, I
am looking for datasources that might provide me this information.
This bid is for $20.  But if you can give me lots of great information
to achieve this task, I will pay more.  I am also willing to pay for
this information if somehow has it and is willing to sell it.
