I am an experienced Linux System Admin, with extensive experience working with Nginx and Amazon Web Services. I have help several people on this site so far with Nginx problems and can help show you how to configure it with no problem using Teamviewer (not sure if I can screen share with Skype as I am using a Fedora Core 20 system, but we can check to see for sure). I am available to do this asap, could even start now if you would like. This would not take very long at all.
