I don't now much about mining, unfortunately, and I'm almost sure that mining is not profitable, at least if you talk about Bitcoin.
It can still be profitable you just need lots of capital to compete in a very dense market. There are lots of big companies who have the lions share of the total hashrate, functioning as a solo miner is not probable without millions invested.
Op, your best bet is too join a pool and contribute your hashrate to the total.
