Something that young you should still be able to find parts in a junkyard. That will be a LOT cheaper than a dealership or even aftermarket. The only thing you might need to think about is if in Ohio you can get parts that aren't already rusted out. There's lots of online yards in places like Texas and California where there's little rust. You might consider having something sent from there. I got a bumper for one of my cars from Texas a few years back and shipping was only $40 or so.
Another possible source, if you're patient, is ebay motors. I know that right now somebody is parting out an '81 Celica (I think) including the doors.
Even if your car is totaled you can usually buy it back from the insurers (I got mine back for $25!
)if you think it is worth it and you want to rescue it. One of mine was "totaled" a few years back simply because for anything over 15 years even the smallest fender bender (in this case another guy rear-ending my car) is more than the car's value. I had some spare parts and ordered others. I got $1400 for the car and spent maybe $600 ($400 labor, $200 parts) plus a few days of my own labor to get it running again and looking almost in its pre-rear-end state.
Something like a door you can do yourself. Just unscrew the hinges and screw the new one on. The fender might be a bit trickier but if you can supply the parts and find a shop willing to work with your parts then it shouldn't set you back too much in labor, especially if you don't have them paint it.
