I have real estate to host, available power, and a fiber optic connection on the East Coast United States.
Cost of Electricity is relatively low
We are building our own deep learning rigs and we are mining. We currently have around 40 - 1080Ti GPUs among others. We charge around $95 per kW per month to our mining clients, and I am sure that we can work out something similar for any of your machines. OR we could build you a machine to spec.
Please DM me for more information if you would like to discuss further.
