Well starting off it was quite low, mabye around $20-40. After about 1-2 months I got about $100. I was never able to get over $1000, though I didn't expect to at that time. I hear when I sold it off, they are making less now. Turns out the people who bought the place were just some kiddies. So their support and services lacked and I guess people left.

But I'd think to support yourself, you'd need to atleast make $1000. I'm not saying $1000 including servers etc.. $1000 "profit" excluding server/domain etc.. costs.
