Rather than starting a general SEO discussion you might be better to post in the review section and let people have a look at the site.
If you generally had 1.5k visitors but then suddenly dropped that isn't a Google dance. Google "dancing" is when a site regularly shifts rankings. It sounds like you may have received a penalty and/or hit by an algorithm update. However I'm not sure of any algo recently rolled out. Check Webmaster tools and see if there are any messages about your site.
