The problem that I have is that my electricity rate is as high as 15c so that I need to find a good alternative that my 1070s makes me a decent profit or at least a break even monthly.
I don't think 15c is such a high electricity rate that you won't be able to make profit.
Go to

In the results, I can see a decent list of coins you would be able to mine and still get a profit. Even if we take into account that these online tools usually overestimate the profit, you should be fine.
