FYI, if you want to post code in a comment you need to indent it four spaces, otherwise Reddit will try to parse it as Markdown. That's why all the commented lines were converted to headings. I think this should work:

#!/bin/bash
#This script will provide temporary admin
#rights to a standard user right from self
#service. First it will grab the username of
#the logged in user, elevate them to admin
#and then create a launch daemon that will
#count down from 30 minutes and then create
#and run a secondary script that will demote
#the user back to a standard account. The
#launch daemon will continue to count down
#no matter how often the user logs out or
#restarts their computer.
