How cheap is the electricity at Mexico?
China has the highest population of miners because electricity is about 3cents/kwh.
Anything above 10cents/kwh won't give you profits because you have to factor in the cost of cooling your mining rigs(the heat produced is high).

Most people prefer Antminer S9 rig to the latest R4 series because it's more efficient however, R4 rig produces less noise and heat.
Mining bitcoins as a solo miner is not so profitable anymore because the halving has reduced the reward, but if you are going into it, consider joining a mining pool to increase your chance of making money.

In addition, you should do some research for some SHA 256 altcoins you can mine in addition to bitcoin e.g KOMODO, Peercoin, Crowncoin etc.
Check worldcoinindex.com for live price updates of the altcoins and the exchanges where they are listed so you can observe for yourself how the market fluctuates.
Chose the altcoin you find profitable, join its mining pool and mine in addition to bitcoin so you can manage to break even in 12 months.
Hope this helps a bit Grin

But I have seen farms here in the US that are gigantic. They must be turning a profit, and there's no way they're paying 3cents/kwh.

And I don't understand why mining as a solo miner is not profitable? I keep seeing people say to join pools, from a business standpoint all this tells me is:your operation is too small, build bigger.
