What are some of the most expensive crops/cash crop to grow to make some serious money in Nigeria.

I have access to 200 hectares of land and am thinking of the best plants to grow.

What do you guys think about the following.

1) Moringa (Seed, oil and leaf)
2) plantain
3) Banana
4) Castor Bean
5) Chilli pepper
6) Grape
7) Coffee
Tea
9) hibiscus

I've also been told that ugu is very Profitable.

If you have experience on any of these pls your suggestion is greatly appreciated. You can also mention the cost and Profitability per hectare. If you know something more profitable pls elaborate.
