Please, stop using only uppercase letters, it hurts my eyes.
In bitcoin mining, the best ASIC (hashrate/Kwu) at the market today is the S9:

Since you didn't include your electricity cost, i guessed it would be around 15 cent/Kwu.
At this moment, current diff, block reward, BTC price and 15cent/kwu:

BTC/day
You'd need about 2500 antminer S9's to make 10 BTC/day
1 S9 costs $1248
+ customs (21% in my country) = $262
+ decent PSU =~ $300
+ Shipping/handling = ??$100??
+ part of a rack = ?
+ part of an A/C unit = ?
+ part of renting a warehouse = ?
I estimate you'd need to invest close to 5 million dollars in order to purchase a farm that makes 10 BTC/day
