Selective sync - keep folder organization

I have tried multiple rules configurations and can't quite get the results I need. The image shows my main working folder "Ads", with a subfolder for each business. I am trying to sync only PDF files from every subfolder of "Ads" while keeping the subfolders intact. The destination to sync to is my Box folder. I also want to sync over new PDFs as they are created as well as updated PDF's as changes are made; and run this sync on a schedule (once a day). It seems like a basic problem but I have spent hours on this and cannot get Hazel to do this consistently. Thank you in advance.
