The best hardware (antminer K5) can get you 5 dollars a day per machine but it's expensive (1500-2000 dollars depending on your provider). Innosilicon A10 can get you 80% of that profit (like 4 dollars a day) for under 500 dollars every machine (pay for themselves in 3-4 months). There are some for under 50 dollars but they get you like half a dollar a day (If your eletricity is cheap) so they're not worth it unless you buy a lot of them.
In any case if you want to live off that you'll need at least 10 machines.
