Create a Small Joomla Content Plugin

I need a small Joomla content plugin creating, from scratch, for Joomla 3.6, that will refresh a Varnish cache when an article is updated. It should be based on the format laid out here: [login to view URL]:Creating_a_content_plugin When an article is saved, the plugin should check: - if the article is published - if the article is displayed on a menu item (see below) The menu item types that articles may be displayed on are: - Single Article - Category Articles (that display categories the article is in) - Category Blog (that display categories the article is in) If any menu items are found that match, and the article is published, the plugin should issue a HTTP request (curl) to the URL(s) of those menu items, with a request method of "PURGE". For deliverables I am looking for the plugin to be provided to me for installation. If you need it, I am happy to set up a development site for you to work on and test, but will implement the code on the production site myself, so simply providing the plugin files is fine too. This is a small project to make a start on outsourcing work, and I will be looking for more work in the future, especially once I find someone reliable to work with.
