Many people in the past have tried something similar such as you with little success. You are pretty much better off just buying the hardware yourself, you will end up making more money.
8KW is not that much power for a farm. If you buy old miners such as KNC Jupiters or S1, which use like 1.5W/Ghs, then those 8KW will only bring you ~5-6Th/s which is only about 10 miners and each of these miners can be bought as low as $50, So all you need is around $1000 and you are good to go. After a few months, buy newer equipment.
I know you have a Hero account, but there is still a trust issue. Even if someone doesn't mind losing an old miner, they end up losing the PSU and paying money to get it shipped to your location.
I am looking to buy my own.
The 8KW limit has been set just because I had that number in mind.
I basicly have unlimited power.. But not unlimited space.
When it comes to the trust issue, then I dont have a problem understanding it.
Sadly there is a lot of scammers around and you need to be carefull.
The people who will have mining equiptment hosted at my place will get my info and phone number to be able to call me 24/7.
Sjenja is gonna send me 2 cubes next week or whenever he has them finished off.
(He lives like 120 kilometers from me.)
Then I will have those setup.
But.. I am trying to buy my own.. Hosting others would just give me a bit more money to work with.
