Develop a Mac Application

Need a workflow to automate my scanned documents process. I am blind and use Apple Products with Voiceover. I attempted to create a process in Hazel, but it is not fully accessible to Voiceover users. I would like to setup some folders that will automatically rename the files dragged to it, tag them and place them in an Evernote notebook and then have those documents deleted to avoid duplicated files. I know this can be done with Folder actions in scripts. I would like to be able to change the tags in the folders once per month as the documents change monthly.
