problem with ignition/transmission?

I've had a problem with starting my 1998 Jeep Cherokee Sport for some time. Sometimes it will start no problem when in the PARK position, (it is an automatic) but occassionally it will do nothing, and I have to jiggle the shifter in PARK or put it in NEUTRAL and jiggle it to get it started. How much might it cost to fix and does this sound like a serious problem or maybe a do-it-yourselfer?
