I hate to be the bearer of bad news but if you are looking at making a profit restoring GTs the simple truth is that the cost or restoring one normally is above it's sale price. A normal return on money spent is between 50% to 75%. I agree with the buy in bulk philosophy, it normally takes two to make one unless you have a surplus of parts.
On a brighter note I know of 10 either for sale or soon to be in your state. The bad side of that is they look to be way overpriced and all need trailering at best.
