I need to do a fresh install of SIerra, but the 12mb download from the store does not have the ability to create an installation media. Where can I download the full size installer?
I get this error when I run the createinstallmedia command
/Applications/Install macOS High Sierra.app does not appear to be a valid OS installer application.
What you have is what is known as a 'stub' installer. Your right it cannot be used to build a bootable USB drive. These stub installers are a pain in the neck.
This article discusses one method - http://osxdaily.com/2017/09/27/download-complete-macos-high-sierra-installer/
However the way I do it is to use a script from here - https://github.com/munki/macadmin-scripts/blob/master/installinstallmacos.py
You run this script in Terminal.app it then lists installers available to download that suit the Mac model you are running on. Currently it lists both High Sierra and Mojave installers. It will download the full installer and create a disk image containing it, you could then mount this disk image and use the enclosed installer to build a bootable USB installer.

Delete the 12Mb install app from your Applications folder. Click on this, https://itunes.apple.com/us/app/macos-high-sierra/id1246284741?ls=1&mt=12
Or did you mean that you want Sierra even though you are posting on the High Sierra community page, if you want Sierra click on this, https://itunes.apple.com/us/app/macos-sierra/id1127487414?ls=1&mt=12
This link just takes me to highsiera on the app store and downloads the stub file again.
thanks, awesome script!
create bootable USB Drive
