re: What are the best trades to get into today?

Two things that never get mentioned in these threads: A/V systems (PA systems; video, etc.)and physical security systems (security cameras, recorders, RFID badge door access, etc.)

Both require some technical knowledge, but can easily be learned independently by a motivated individual. And both are technologies that many mid-to-large companies ($$) need.

From what I've witnessed, these are two trades that have very high ceilings because companies love contractors who are very good, and there are tons of contractors who aren't very good. Very ripe situations for someone who's smart and works hard.
