Replace Windows File Date Modified Timestamp With Date In File

I am looking for a Windows script (batch, VB, PowerShell) that scans through a specified directory with sub-directories and replaces the date modified timestamp of each file with a value found within each file: I need the script to do the following: 1. Check if file contents begins with "MIME-Version" or "Delivered-To". 2. If file begins with "MIME-Version" perform the following steps: A. Extract the date timestamp from line 2 (see example below and note that sometimes the day date is one [1] digit else it is two [2] digits): MIME-Version: 1.0 Received: by [login to view URL] with HTTP; Thu, 10 Aug 2017 16:43:01 -0700 (PDT) B. Tokenize the date timestamp into MM DD YYY hh:mm AM/PM C. Adjust time such as -0700 (PDT) into Central Time D. Change date modified timestamp of file to the adjusted time. -OR- If file begins with "Delivered-To" perform the following steps A. Extract the date timestamp from line 3 (see example below and note that sometimes the day date is one [1] digit else it is two [2] digits): Delivered-To: [login to view URL] Received: by [login to view URL] with SMTP id kj3csp1973383qcb; Fri, 2 Jan 2015 17:13:55 -0800 (PST) B. Tokenize the date timestamp into MM DD YYY hh:mm AM/PM C. Adjust time such as -0700 (PDT) into Central Time D. Change date modified timestamp of file to the adjusted time. 3. The script should process only a specific file type. In this case it is *.eml files. 4. The script should be able to skip files that do not start with either "MIME-Version" or "Delivered-To" AND files that may be missing date timestamps on the specified corresponding lines. 5. The script should recurse the files and sub-directories of a specified directory. 6. The script should produce a log of what files were successfully processed and or skipped. 7. The script should be able to tell which files it has already processed in case the script must be resumed. 8. The script should replace the date modified timestamp of each file with the adjusted date reference as specified in step 2. Is this something you would be willing to help me with? If so, how much would you charge and when would you expect it to be delivered? I look forward to working with you. Kind regards, Paul Luckett
