How do I discover (or What are) the top 50 industries, that rely on business to
business sales lead generation? As well as, their customer acquistion
cost?

For a $50.00 question I am rather supprised that no one has even
attempted to respond.  I am in Business To Business sales.  I am in
Los Angeles California.  I have done hours of reasearch to try and
gain Leads, find out who uses a specific product and who the contacts
at the company involved in purchasing my product would be.

I would venture to guess that every single company relies on business
to business sales.

I know this may be stating the obvious however, business does not seem
to move forward without the ability to gain new customers.
