How much marketing budget should I spend on a facebook campaign?

why you should bother to pay if you can get it for free, It costs NOTHING to run this entire business. And when I say nothing, I really mean nothing! This is something that really hooked me with this model of making money, and is a benefit not to be understated. Since you’re using free Facebook Fan Pages and not Facebook Advertising, your clicks cost nothing. You can promote anything as an affiliate and make as much money as you want, and no-one has any claim to any of it. This is a huge benefit because it means you can build up your income at your own pace,without racking up bills and overheads that need paying.
