Maybe KWWHunction should act like a middle man in terms of payments. KWWHunction holds the payment for 30 days and then release it. I mean KWWHunction is what both customer and a seller would trust on rather than trusting each other.

Yea ^^^^ that sounds weird but hey i m just throwing ideas.

BTW Business age check would be hard for new comers. But yea it will help us get stable services.
