Honestly, I don't think children should be involved in your dating life. Until there is a serious commitment made (Engagement, commitment to get married, etc.) your daughter does not need to meet him. Once a commitment is made, then you can start working on family time. My best friend's psychologist told her that when she was dealing with a divorce, and I have always agreed with that advice. Kids get attached, they end up getting hurt. They are not adults and can't understand fully. You have only been split for 9 months. Meaning, you barely know this guy. Your daughter has barely had time to adjust. Bad idea, in my opinion. I think you should talk to a family counselor about how to approach relationships in a way that doesn't hurt your daughter. (I know it can be really new territory, professional advice always helps.)
