Custom Wordpress Delete Media Function

I’m looking for someone to write a hook/function for my theme in Wordpress 4. We are using s2Member plugin to control access to pages and uploaded files. When an admin adds a file to a custom post type (file field from Advanced Custom Fields), a custom filter in our [login to view URL] file changes the path of the file on upload so the file is placed in a special directory. That structure is /plugins/s2member-files/access-s2member-ccap-{username}/{file_extention}/[login to view URL] This seems to work well however it breaks deleting attachments from the Media Library. The attachment post is deleted, but not the files in their sub-folders. I need someone to write some code that we can place in our functions file that does these things when the admin deletes an attachment from the Media Library: 1. Get the post ID of the attachment, get the parent post ID 2. Get the value of meta key=s2member_ccaps_req of the parent post (which is stored as array) 3. Get the extension of the file attachment. 4. Check whether the parent post is a custom type of either “clientdocument” or “clientresource”. If it is neither, do nothing to the delete attachment URL. 5. If the parent post custom type does match either “clientdocument” or “clientresource”, change the path of the file to be deleted to: /plugins/s2member-files/access-s2member-ccap-{s2member_ccaps_req}/{file_extention}/[login to view URL]
