Learning to do things right and learning what things to not touch isn't that hard.

If you limit yourself to simple work like replacing outlets, switches, and hardwired lamps, that's most of the likely electrical work for an existing house. Call a profesional for new circuits and maybe for replacing breakers; IMHO, it's a scary box, but the work is straight forward, so I'll replace breakers, but I would (and have) definitely call out for a breaker box replacement.
