I doubt you'd get much donations for something viewers aren't getting back besides basic entertainment that they may not even know you will even fulfill. I'd recommend you get good at a MC skill, like Chub1997 said, like Terraforming, Skinning, creating Texturepacks, etc, and produce them in a shop in exchange for money. Never ask too much, but always give users something they'll enjoy for their money. Also, make sure you're good.
