I have been doing this for sixty years and I will say what you want is do able but not likely. The first thing you need to do is join a club or chapter and meet the people. You need to join a club where the members work on their cars and understand how to evaluate a car. You want some one who can go with you to evaluate the car. You seem to be looking at "T" but could you evaluate a "T" and drive it. What ever you buy will probably need tires which is another $500 up front. The touring you listed requires a top and interior. Have you ever installed these. The touring listed says engine rebuilt but does not a have a coil box. I would suggest you start a little smaller in a speedster and learn the ropes, trade it or sell it and move up the ladder. Another advantage to a club is that a member may have a car they are not using which they will allow you to purchase more in your budget.
