Advertising. But not Googleads or whatever. Depending on if your audience is niche enough for this, approach people directly and ask for a block sum. This works especially well for local sites where you can just walk into local shops and up to local business people at events and ask directly. And as others have said, reduce costs, host elsewhere really cheap and only scale up IF needed. Because you probably need to actually build up an audience before you can do this.
