McAfee Agent and McAfee Endpoint pkg as Jamf policies

There are a few existing threads about putting the McAfee Agent install script into a package and creating a policy for deployment.

However, I have been having issues getting this to work. Full transparency I am not that well versed in scripting.

To install the McAfee Endpoint security software the McAfee agent needs to be installed by running a script. We currently do this manually after imaging by doing the following:
Take install.sh file from flash drive and move to desktop
in Terminal:

cd desktop
sudo chmod +x install.sh
enter password
sudo ./install.sh -i

My hope is to create a policy that automates this and installs the Agent, and then have a second policy (or bundled into one) that installs the endpoint security software.

The biggest issue is that most of the existing threads, answers state, just add a post install script, however I don't know enough about scripting to just write one, or know what needs to be changed from a provided example. Also, our configurations create the main user account as a standard user and we have hidden local admin account, so the script would need to work in this scenario.
