The way things are going you might be able to offer hosting even to 1 or 2 clients who have a medium sized farm of their own.

Best way to proceed is to get all your personal machines up and running. Once you have this set up and planned it's time to see what you have left to offer electrical wise; out to either a partner or as a hosting service.
I've never hosted equipment but another consideration will be making sure you have a solid network set up.

Anyone who does consider sending gear your way will want to see that the site is prepared to handle the miners. This would include providing dust free intake air and appropriate levels of air movement to remove waste heat.

This summer will give you a great indication of what you need to do because those 20 S9's are going to add a lot of extra heat so it will be a good way to learn what you need to plan out moving forward.

In the end sounds like a great place to set up a farm, I was reading about a medium to large sized mine operating there last week. Beautiful country as well came through last summer for the fist time on a family vacation.
