Based on my calculations Ethereum Cloud Mining is not profitable unless you can rent it much more cheaply than I've been able to find anywhere. You're better off just buying ETH on an exchange and holding it.

The Ethereum mining profitability calculators I've seen assume the network hashrate is static, when it's been growing rather rapidly. This means you are sure to OVERESTIMATE the amount of ETH mined.

Right now I wouldn't be willing to pay more than around $14 per MH/s of hashing power for a year. I'm not aware of any cloud miners that offer pricing anywhere close to that.
