How i make my own mining project

Hello vosk, I am very happy to join a site and talk to you. I want to consult you in a cryptocurrency mining project. I want to arrange 300 mining machines, but I do not have experience in the space that I will need, the required electricity, or the ideal ventilation. I want to arrange a warehouse for mining, but I do not know the required space. The device that I will order is Antminer E9 (3Gh/s) Can you tell me the requirements for processing in all respects according to your experience in mining? Thank you very much. Best regards Ali Ayoub
