Look for another car that has a blown motor or trans and do the swap. This would be cheaper in the long run and you can do some detailing in the motor compartment when you install the motor and trans. Plus you would have a parts car too which in turn can save you quite a bit of money if you keep the car for awhile. If there is as much rust as you say then she would be a waste of time to do anything with it. Good luck!!!
