21 and want to move out!?

I am 21 and want to get a place of my own. I have no money and I am on a temporary job, earning £5.60 per hour. I do not work full time some weeks, but I do most. Starting at the beginning, can someone please tell me exactly what I need to do to buy my own place. As much detail as possible please, and no jokes, as this is a serious question. Thank you.
