Others submit large invoices, whether video results are obtained or not. Josh will endeavor to give you useful information that helps you make the right decision with every investigation. 

Joshua worked for a nationwide company for several years, and  consistently made the top investigator list. He became frustrated with the strong focus on ‘billable hours’ rather than quality results.
