Officiant for LGBT wedding?

My fiancé and I are getting married next year and have started thinking about who is going to marry us. We are both men. Neither of us is particularly religious (thanks Catholic upbringing for all that trauma) and we don't have any kind of religious figure in our lives that could perform the ceremony. Wondering if anyone has experience with this or any suggestions of someone to officiate? We want to find someone who is excited for our marriage, not just tolerating it.
