Yeah, it really is super easy. You won't kill yourself unless your an idiot, but you might not figure that out in time... It really is easy, if you understand household wiring, don't be afraid. There isn't really any reason to be more afraid of 240 vs 120, both need respect but both are manageable for a novice. There is plenty of information on the internet (I would however suggest an electrical forum not a homebrew forum...) and your local hardware store. The savings of hiring somebody will likely be substantial but the knowledge is priceless...
