Don't close it, I'm talking to someone in here. Anyway, I wanted to inquire how long one of these commissions takes you so I could tell you what tiny fraction of a percentage of minimum wage you're earning - you should develop your skills and charge more! It will attract a different type of buyer (... though getting payment first is always sensible).
Nothing wrong with asking for the money you both agreed he would give you, but you screwed yourself over by sitting around waiting for months without saying anything. You should have asked for his payment at the same time you gave him the work, at the very least. And if he didn't give it to you, you should have reminded him he still owes you each week until he paid you. You also don't need to make up a fee since it's just 10 points, which is almost nothing itself and you already gave him the work. Unless he voluntarily gives you the Points, you're screwed and can't do anything about it other than tell your friends not to take any requests from him. Let this be a lesson.
