Starting a gasoline motor

Ok, this should be simple and I have seen the circuits that allow
relay control, yet I would like some little peace of mind that 300
amps aren't going to end up coursing through my stamp's fragile
little semiconductor body.
Therefore, I want to use the stamp to do some math stuff (I'll figure
out the code) and at a predetermined time send a control pin high
that will- through this mystical circuit- cause a 12 volt solenoid to
engage. This will then turn a starter motor on a gasoline engine-
just like starting your lawnmower- cause that's exactly what it is.
Again, fairly easy task- I would just like to hear from someone that
has worked with the higher amperages and been able to provide
isolation from the Stamp to determine the type of circuit and
hardware I need.
Thanks,
Tim

Magnecraft, etc. They all have output modules rated for AC and DC
loads. I do this stuff with AC loads (mostly lighting and valve
automation control) all the time.
Good Luck,
Guy
