Yes you definitely have to get it installed by a licensed electrician (and possibly approved then by the local utility) if you are going to backfeed your own house.
It is good that people are aware of the risk, but in reality the risk is quite low. It is standard procedure for a lineman to ground a line he's about to work on, to mitigate the risk of any power source feeding it. But I'd never advocate a DIY setup. But damn near everyone I know with a portable generator has a suicide cord and just flips the mains. Ah well.
