Lol, I've worked once with that guy last year and I didn't give him the project, his name wasn't Project77 before. He wanted the payment to be done outside freelancer though I rejected and I said that I have to get the milestone first before I will give the project. You should not deal that easily with employers with unconfirmed payment (when the dollar symbol of his profile is gray, and there is an "x" mark on the payment meaning he hasn't transferred money yet to his account), and 0 reviews. Lesson learned to my freelancing mate. Sad to say you won't get any of the %50 because the only way you get secured with payment is through milestones.
