Just my two cents of advice...

If you are even still slightly confused about how to proceed in getting into Bitcoin mining, your best bet is to start SLOWLY and get a single S9 before jumping into the deep end of the swimming pool.

Learn how to do everything you will need to do with multiple miners on the single S9. Then if it seems like something you can deal with
- electrical, cooling, ventilation [ removing HOT air from your mining area is paramount. Do not just think using an air conditioner is a simple answer; it's not],
networking, setting up and mining to your own private wallet, transferring coins to and from an exchange, and the many other chores you will need to master to be successful - then you can expand.

I'm just speaking from experience. Read, read, read anything and everything on this forum's threads regarding hardware, mining software (Awesome Miner or something similar), routing and networks, troubleshooting, etc. And many more topics. It's the little things that don't occur off the top of your head at first.

In the long run you will be very thankful for the accumulated knowledge about the whole process you will have obtained.

Once you KNOW exactly what you are doing, then you can knowledgeably take on partners/associates. Just my thoughts on how I would do it.

Good luck.

Hi,

Free power is one thing.  A megawatt of free power is something else again.  If you can arrange for a megawatt of free power, I would be willing to join you anywhere in the world (subject to your government's acceptance of a US Passport) and help you to build a mining operation, in exchange for 50% of the first year's production. 

Let me know if you're interested.

This stuff costs real money and produces real value.  Free advice is worth what you pay for it.
