Sure. But the idea is to do a quick ice breaker project that can later turn into a larger one down the road. Hence in that case a $500 - $2000 structured project makes sense, I think.
Businesses are in business to make money. If you can provide value (I'm not saying you can't) and they see an ROI on their money, they'll pay. They want a solution to their problem AND they want to work with someone they like and trust.
