Service providers categories

March 15th, 2010
Where can I find a database containing a detailed break-down of service providers (e.g. accountants, lawyers, doctors). My requirements are: - Consumers oriented directory (e.g. Google directories). - Comprehensive, heirarchical structure - For each service, a list of associated expertise. For example, if we take an architect the line of expertise can be interior design, construction, decoration, etc. - More refined than the NAICS system - Features quality performance components for each service. For example a medical service given by a doctor can be measured in levels of: professional expertise, clinic, human relation, treatment outcome, cost, etc.
