I've spoken to multiple Handymen type people, one of which has a "Baby Proofer" business, who said they have been making money hand over fist replacing ordinary receptacles with Tamper Proof models. They use the NEC as a promotional tool (or scare tactic), yet they aren't licensed electrician. A whole house of receptacles could lead to a nice profit for a handyman, even as he undercuts most EC's.
In your jurisdiction, what is the most (if any) electrical work a non-licensed person can do? Replace receptacles or light switches? Change light fixture? etc.
