My inquiry centers on companies that deal with emergency management.
For example, they provide services to local and state municipalities
after hurricanes such as debris management and/or they might help
local and state municipalities apply for funds from FEMA and State
Agencies. The services they offer are both actual and technical and
can cover a broad range.

Their SIC codes might be 8711, 8741 or  8742. They might also have
NAICS codes such as 541330, 541611 or 541612. A single company might
provide services that fall under all of theses codes and more.

Examples of companies that provide one or more of these services are
PBS&J, Global Options and Malcolm Pirnie. They are engineering firms.
Look at them in order to understand the type of company I am
interested in.

I have several questions:
1. A list of all of these companies (small, large, public and private)
in the US and possibly Europe. But US companies are my primary
interest.
2. I want to know if any of these companies has been bought or sold
during the last five years.
3. If so, I want to know the REAL details about the sale such as
selling price, valuation, company financials. Etc., all the business
factors. It is the details of the sale I want to see, that just a
press release saying company A bought Company B, but the details.
