Is there any interest in a community mining farm? I currently have roughly 250+kw worth of capacity in Washington state with extremely competitive electricity rates. I had originally planned on mining internally with hardware I already own, but with the recent difficulty adjustments, I am realizing I would be better off leasing the space to customers with more efficient hardware. At $50 per kw month I would be more profitable than running my 1 watt per GH equipment.
It may not affect you but there is some pressure to raise the electricity price for Bitcoin miners around the Wenatchee area in Washington State. There is also a moratorium by Chelan PUB till at least October on new small Bitcoin mining farms.

Individuals just do not have access to state-of-the art miners. Unless something changes it will be almost impossible for an individual to have an ROI after July, when total mining income halves.
Trust will also be an issue. There have been a number of people try to do something like you but in the end nothing came of their plans.
I experienced first hand dealing with Chelan PUD. Their moratorium was expanded 2 days after I signed a lease for the initial location I was planning on building out. They wouldn't give me any power because of it. In hindsight it was actually a blessing in disguise. Miners in Chelan are going to see their rates hiked up to almost double what they are now which will be around 5 cents. Needless to say there are a lot of pissed off miners about it. I am in a neighboring county and although I can not say with 100% certainty that rates will not go up, they were just recently voted on and the rate adjustments have been set for the next 10 years.
You have a point about ROI challenges ahead but with current S7 pricing I wouldn't say individuals don't have access to state of the art miners. There might not be any interest, in which case I will just continue mining internally.
