Good afternoon. I have a Custom List in SharePoint. I need to traverse the entire list. For each row in the list, I need to create a folder structure. For example, assume that the field in the row being traversed contains the following fields.

sot, Graphic Design, rhoward, Graphic Design Technology Reviewers, 10/1/15, 12:00:00

I need to create a porcess using SharePoint, PowerShell or InfoPath (or a combination of these tools) that will (upon execution) create the following folder structure and give rhoward owner rights to it:

sot
- Graphic Design
    - Howard
         - AppFolder
         - Teaching Documents
         - Testing Committee

At 12:00 midnight on 10/1/15, rhoward's access would be changed to read and the group named Graphic Design Technology Reviewers would be given owner rights to the entire folder structure. The name "Howard" is the last name of the user named "rhoward". I would like to use SPSite or another SharePoint construct to obtain the last name based on the username. Can someone please point me to a tutorial that explains how to accomplish this? I am a web developer, and I have not used InfoPath before. I plan to learn it as I complete this project. Thanks in advance.

Thank you.
