Nicehash is the gateway to rentals, but the deposits and fee's make renting from these guys unideal as well as a questionable history of fraud hence no one's mentioned em thus far.
maybe check this alternative out (my reference included)
MiningRigRentals.com - Are these the mining rentals you are talking about mate have you tried putting money into it? if your answer is yes, how are you? I hope the real answer is not because you will get a commission here.
Because as far as I know, at this time I don't see anyone who can say that these types of mining are profitable just by using their website platforms.
