Have you tried looking at Nicehash yet? I see that the rate per 1TH/s of Quark hashing on the site is currently 0.0417BTC/TH, seems more viable to rent hash that way and youll likely be able to start mining quicker than renting from someone on this forum. Just a suggestion.
I need constant delivery of 2 TH/s, hence why i am going for 0.05 BTC/TH/day
