Evil Turkey - While I'm not one to discourage someone else from taking on a job of this magnitude, I would estimate the cost and time spent will not be worth it in the end. It most likely will be neccesary to replace the floors, floor supports, outer rockers, outer wheel houses, etc. just for starters. At some point in the past, someone reinforced the front frame rails and replaced some metal, from what I can see. These cars have to be disected and turned inside out to get access to all the hidden rust. Sure you could make this car roadworthy once again, but first ask yourself if it really is worth the cost or time spent. In the end you are much better off starting off with a better condition car.
