The last meeting of the month here (I go to several groups) is a speaker's meeting. I attended a number of them until I heard one guy tell a story that was very similar to mine. He experience with early drinking, career successes and failures..many other things.
One evening I approached him and just said, I need someone to help me work the steps and need a new sponsor. He just said "would you like me to be your sponsor?" And that was that. He's a great guy, long sobriety, great advice, good listener.
Good luck with that - I thinks it helps to listen to a lot of different people and try to find one you can identify most with their story.
