Should I Start Mining? (help!!)

So I've been making a fair amount of money trading crypto and I'm considering making the investment into staring mining.

Electricity is relatively inexpensive here (Ohio) (5.75 cents/kwh)

I've built computers before but want to do this right. I was thinking of building an 8-10 GPU rig with an open air aluminum frame to see what I'm getting into. I've been mining Monero a bit with my 4 year old computer and making about $2 per day with one older GPU.

Could anyone give me an idea of how much I could make per day mining with an 8-10 GPU rig (and which GPUs)?

Also if I get into making multiple rigs what are the best software options for mining with GPU rigs? Eventually I guess I might potentially get some Antminers if I really get into this.

Any advice is greatly appreciated!
