If I were you I would invest into a bigger miner. Something that can produce at least 200GH otherwise you won't be making any money. Check out my website for more info if you want.

I post video reviews of unboxing and actual earning on my website. I'll provide a link to a miner which in my opinion is the best option at this point.

I only have one Antminer however looking to invest in many more. I have other mining rigs but antminer is by far the quitest one out there here is a vid of me unboxing it.
