Just a heads up, I (and many others I guess) got scammed buying hosted miners. It's hard to use escrow for these so be carefull
It's all good for one or two months, then one morning you wake up and realize there's no hash, no contact info and all, so be carefull.
What I'm saying is don't buy if it's not in a known facility (colohub, toomin bros etc.) where you can contact the host and he can transfer ownership of the machines to you
Good luck on your sale mate !
