Wordpress Post to Craigslist HTML Generator

Hello there, IN SHORT, OUR REQUIREMENTS: Somewhere in the post editor in the WP-Admin there needs to be an "export to craigslist" button that will create an HTML rendition of their post, including a large image thumbnail that links to the post on the website. That HTML template will need to be consistently styled with the same layout for each time a post is exported. This project is for a small car dealership. They have an inventory on their Wordpress website, but have been hand-coding their Craigslist ads. They want a simple button somewhere in the back-end of their site where they can click and generate their Wordpress post to an HTML Craigslist ad which they can then copy/paste into Craigslist. Each of their car entries have some custom field parameters (mileage, transmission, etc which are entered in the post creation page using custom fields, which pulls this information and uses code to display it on the posts), a description, and a featured image. Here is an example of a Craigslist ad they created. They would like this plugin to create something similar: [login to view URL] and here is the original post on their website: [login to view URL] additional notes: It would be nice if the code was commented in a way so that the HTML template could be easily modified by a web designer in the future if they chose to style their craigslist ads further (ie: change colours, change the header banner, etc.) Thank you very much for looking! We are hoping to get this done as soon as possible. ***PLEASE NOTE: We pay on time and we expect our freelancers to deliver on time. If you cannot commit to project timelines and deadlines, please do not bid on this project. Our timeline for this project is 10 days. Thank you.
