Check if your state requires a guard card. If so spend 100 bucks get one, it not go apply to a security company.

Make anywhere form 20 bucks an hour to 30 bucks an hour depending on where you are.

The work is basically brain dead and has zero physical requirements beyond being able to stand, walk and breath at the same time.

Security work is mostly paper work and staying awake. If you want to invest into it then armed work can make 30-40 an hour and if you REALLY invest into it the nicer companies with high end contracts basically have no upper limit on how much you can make.

But for your run of the mill guard, your basically just a modern day butler. You just watch shit, fill out reports and call the cops for the property owner when things actually happen.
