Remote hosting is intrinsically risky and there isn't a way around it other than escrowed $/btc for the value of hardware held.
with your reputation, no one will trust you. why not buy the miners and set them up yourself? You said you have cheap electricity and you can earn a lot of money? If you lack of capital, you could find some investors in your local.
I have cheap electricity and I could find the capital, but I don’t want to invest 12-15K more in the Bitcoin mining industry. I have 6 miners and it's the amount I'm comfortable with for now.
Since I have space and cheap power, I'd like to earn some money by taking care of miners and by slowly growing my own farm.
