This stuff tends to be pricey - couple of hundy on the low end in my experience. search for "automatic transfer switch" usually start out at about 100 amps.
how big of a load are you switching - another factor will be current draw - are you ok with the switching / sensing element drawing down the 12 volt side? does it need to be UL approved or will something home made do?
I have some bits and pieces laying around if you get stuck.
