Wanting to learn the business so you can micro-manage your manager sounds like a recipe for disaster.
That or sell it to a big coffee producer and go about your life doing things you’re good at.
I would assume labor is cheap where you’re from, the problem might be with selling your product locally.
Think of one of the simpler tasks. Say you need to fertilize the trees. When is the right time? What is the right amount? How many people do you need to fertilize 8000 trees in time? How do you finance that, including purchasing the fertilizer? Are you even allowed to purchase that much fertilizer (it's been often abused to make car bombs)?
No idea whether fertilizing is even a thing with coffee, but other tasks won't be much simpler.
If you can't hire one, is taking on a temporary partner (for a cut off the profit) an option?
At the very least they could point you in the right direction to get started, and maybe even know someone you could hire.
I'm skeptical that you're in a position where you can afford to fail, short of edge cases like "I just let the land lie fallow and pump no money whatsoever into it" or "I am a multi-millionaire already without the plantation".
You experiment. It takes a lot of time, yes, but it’s not that difficult.
I find your answer and many other here overly pessimistic and unkind. Not every thing is about hustling a business to perfection and on the first try.
A failed experiment might cost you 8000 trees. It takes a massive amount of time, and money, to re-launch an experiment of this scale. And every re-launch, you restart the 3-4 year clock until trees are mature enough to harvest.
When you quoted me, you left out the part about how to finance all of this.

With an 8000 tree farm, that point is you very very likely have only one try.
