Heck, 8k trees is a lot. Definitely find a professional. Growing coffee is exceptionally difficult.

Do you have an idea which crops have been planted? Is the plantation in a favorable location (altitude, weather)?

Depending on both, you should become clear about whether you want to produce commodity coffee or specialty coffee. The latter is more difficult to produce, but also more profitable.

If you're going the specialty route, it may even be fruitful (hah!) to get in contact with content creators. They usually have useful contacts in the industry, and they might be willing to connect you.

In any case, try to get in touch with European roasters, as they usually value traceability and prefer to roast single origin coffees.

Best of luck! And enjoy the journey.

Oh, and if you had your first batch, please drop me a message. I know a few local roasters (Germany) that may be interested in new sources. :-)
