Everybody should be able to wire a new socket into a lamp and install a lighting fixture into an existing box. It's really not hard at all, and you can do amazing things once you know even the slightest bit about wiring (not to mention saving tons of money on electricians). Electricity scares people when they don't know anything about it in the same way that water scares people who don't know how to swim. Home depot has a great book called wiring 1-2-3 that should tell you everything you need to know, plus it has pictures and tells you exactly what to be careful of.
