The exception in the second group would be those that have the proper training and skill sets to write an abatement plan for a mold damaged structure, but these folks are not easy to come by and tend to work for the environmental consulting firms. They have advanced training and many have specialized degrees or certifications from accredited schools. Just handing a client a "Mold Report" does nothing for anyone, a true abatement plan is needed. The abatement plan is what the mold abatement contractor goes by to clean the structure. It is the road map so to speak of how and what needs to be done.
The EPA has a great pamphlet that tells consumers what they need to do when they find mold. It is full of common sense and not hyperbole. http://www.epa.gov/mold/pdfs/moldguide.pdf
