Welcome!
I would want to hunt the largest places you can. Stay with indigenous species as much as possible. My personal preference is to avoid the higher priced species such as Sable, Roan, Nyala as they tend to be in smaller more closely managed pens. I prefer to wait for opportunities to hunt them in wild areas.
Consider some night hunting. Limpopo has a few of the tiny ten and many of the silent seven.... Great fun!
How much space do you have for taxidermy? Is your budget pretty healthy? If I was starting over I would be much more selective on what I had mounted. And really consider just pictures for a lot.
By the time we add up dip and pack, shipping, taxidermy, bases, shipping within the US. Handling hassles, and the inevitable need for a trophy room.... we are going to be in way over a million usd. Possibly two.... Think about all the extra hunting you can do. Especially post pandemic with shipping, labor, building, taxidermy costs all very inflated from what they were..... While hunts are still priced pretty close to where they were.
