Yes, but you have to know that you won't be at 100% at all the time.
If a server costs you $100 and you want to fit 100 customers that pay $1.5, you cant expect that wou will have a profit of $50 every month.

If you see it as a way of promoting, i fully understand you.

Selling hosting here on KWWHunction wouldn't be ideal for you, as it can harm your reputation. (KWWHunction = warez junction).

Anyway, good luck
