Any reason the plugin itself doesn't work for you? It does require you to actually click the button to create the post, although I assume it can be automated for Ghost (we just tended to make it a little more generic so it works with WordPress, etc.)
@kyletryon I was thinking of using AWS too, sounds like a very appealing idea. I ended up going with a company called "Digital Ocean" And just recently got it all working on their Droplet service. Look into them too.
