Wordpress Remote Posting - repost

Hello Freelancers! CONTEXT: Currently, I already have a cron jon plugin built by a previous freelancer. It is a well-built built plugin that works with the cron-job in cPanel to deliver post content from the one central master site to whichever mirror site that is added within the plugin settings page - see screenshots below. How this works it that the central master site would contain posts and it will update similar posts on its mirror sites. It recognizes similar posts based on Wordpress post ID. The cron job only updates the similar posts that are present on the mirror site and does not add any new posts. REQUIREMENTS: 1. REMOTE POSTING ABILITY: This remote posting ability can be in the form of a separate plugin or built within the current cron job plugin that I have. If you think it is better to build a separate plugin, feel free to make use of certain parts of this current cron job plugin to aid you in the development of the remote posting plugin as both would make use of mirror sites. I would like to have the ability to ADD posts and other XML content remotely from my central master site over to the mirror sites. Step 1: Select the post type Step 2: Select which individual post to remote post Step 3: Select which mirror site to add this individual post to All selections are done from a drop down list/menu 2. SETUP CRON JOB As my previous freelancer is no longer responding, I have no idea how to setup a simple cron job for use with the current cron job plugin. I will need you to provide me with the steps as to how to setup the cron job. Please bid only if you are confident in doing this project. Kindly take a look at the attached screenshots for more details on the current cron job plugin that we already have. Before we proceed with the project, feel free to message me if you have any questions to ask about the project. From there, you can decide if you would like to take on this project or not.
