Wait a minute, are we talking about:
1. Getting the car on the road and driveable and reliable and cheaply maintainable? or,
2. Restoring it to a new-ish car for show and/or go?
If 1. go for it, it's cheap and easy, don't be intimidated, buy some tools and parts from a junkyard or NAPA and get dirty and have fun. But, if 2. then forget it, it will cost way more than you thought and it will take way more time than you thought, and since the car has to be off the road for a long time, you will eventually learn to hate the big ugly hunk of crap, wish for your garage space back, beg for someone to take it away for free, and curse it as you try to sleep at night. If you want a fully restored beautiful classic car, buy one. If you want a cheap and fun do-it-yourself older car, get one in reasonably good condition (sounds like you already have this), then do what it takes to make it safe and reliable and just enjoy it and leave it at that.
