Since you you say you have a lot of money and you say you want a good pond for recreational fishing, I'd settle for nothing less than a pond of 2 acres or bigger, and 10 acres makes a lot more sense. You can't make a 1/2 acre pond into an ideal fishing pond in the sense that you would have a self-sustaining fishery....which is what Bill Cody is saying. Stocking apex predators in very small numbers and then catching the same stocked apex predators back out again is not recreational fishing according to most folks who usually fish in natural bodies of water.
Bill Cody says "A 0.5 AC CLEAR WATER POND IMO WILL NOT PRODUCE FOR HARVEST MORE THAN 2 LBS OF PREDATOR AND 10 LBS OF PANFISH PER 1/2 ACRE. IF THE CP AER NOT SPAWNING - RECRUITING THEIR HARVEST WILL BE A PUT & TAKE SITUATION"
Having your buddies over and breaking out the fishing poles to fish for a 2 pound predator is not on a parallel track with a goal of having a ideal fishing pond.
As many pond experts have taught me over the few months that I've tried to learn from this awesome forum, the best time spent is the time spent thinking of what your priorities are and then setting REALISTIC goals. If money is not the limiting factor then perhaps you would do better with a single larger pond or 2 larger ponds with the same breakout of apex predators that you describe above.
