My concern is the risk involved. There is effectively no way to test the health of a natural gas well. The pressure and line size can only give you a rough idea. What if I commit to hosting a bunch of miners and a month or two later the well stops producing? What if a generator fails and leads to downtime? What if a weather or other event causes peoples equipment to get destroyed or stolen? There is a lot of liability and risk involved that I do not feel comfortable with offloading to others, with nothing short of hiring a lawyer to draft a contract.
Yea, don't host. It not a venture to start unless you have all the capital for logistic setup and liability.
I forget what you said your budget was or hash target but with free power you could grab any unit and power them up. New, cheap hardware is A951, S9i. The T2T 25T is decently priced as well but double the price. You can still find some cheap 841's floating around.
