According to me it's not a good idea to start a mining farm because now a days mining is not Profitable at all and you won't get Profit in Mining because of the halving passed last year made the Mining not Profitable So I Suggest you to don't waste your money in mining, invest it in another business.......
This was from year ago. Mining IS profitable even after halving, but you need to be real professional with huge money to risk.
Especially chip manufacturer's have high changes to compete in this business, because they have ways to get a lot of good quality, personalised chip's quite cheap compared to other people.
There are thousands people (around the world) that are more suitable to do mining business than you. Keep that in mind.
