Oh, I read this too late...I am too stupid. I also reply in his marketing post. He found me in the last few days at my previous Kickstarter campaign. He did drive me some sales with a % of profit which I think it was worth. He was so kind that we chat like a friend throughout this year without any additional fee. So for my latest coming Kickstarter campaign, I want to do something big! He requests a $2500 upfront and I think it worths a try. After I paid I have nothing and he disappeared after that, not just a few days but a month with few almost useless comments every week from email but 0 subscribers. But now he disappeared. My heart is broken and my wallet is empty
