Toni, you need to look at the definition of "commercial use".  What you're
wantint to do actually is not legal.  I'm not even sure what kind of gear you're
talking about transmitting on 414 mHz with but that's not in anyone's band that
consumers are supposed to be using.  Particularly on lower frequencies if you
get a bit of skip on some ham band you could end up transmitting a lot further
than you intend.

You might want to look at the regulations about transmitting as it is stated
that "experimentation" is encouraged but there are serious limitations
concerning "personal use".  You can get Part 95 from Handi-Hams which is the
legal material the FCC uses to control all of this.
