Do you know of any hosting companies that can do this?
Related to your question.
I have heard colocation services for our mining machine, but it was a few years ago, and I don't know how trustworthy they are. You can Google it.
Other than that, I agree with
sjyi opinion:
So you're looking for a colo which has a lower electric rate to run your miners so you can pay for their service for less than what you pay for your electricity. If you're not making money by running your miners at your site due to electric rate, you'll likely end up paying someone more because those companies are looking for you to pay not only electricity, but also their overhead to run your machines.
It would be easier and less costly for you to still run it or unplug it until the coin price goes up.
