If you are a nickle host it would be hard to see a profit in the first year. If you sell VPS or Dedicated I can see it possibly work. You can even sell services such as mods and fixes. Hosting guys need to virtualize. That's where it's all going. The cloud gents, the cloud.
It does not matter what prices or services you are charging as a host, BoonEx would like to receive $100 (+ ongoing commission interest also preferred) commission per referral. No matter what you are charging this an extreme amount of money and takes time to recoup the costs.
