You don’t. There is almost no profit in agriculture for farmers. Your best bet is provide high quality specialty organic foods to local restaurants farmers markets and csa then and run workshops and videos selling services teaching others how to do small scale farming. Still you will probably earn less per hour than a fast food worker in Seattle.

Things like terrain, climate, capital and time you have, labor costs, water access, routes to market are huge. You can't answer this without knowing far more.

See what other locals are doing. Probably something similar.

Where is this place at? I work in agriculture. You could look at the best crops for that part of your country. If you do it right you could make good money.
