Presentor

I am looking for a presentor for the 7th of December. My work is holding a murder mystery evening. And we need a PRESENTOR. We have the script but the evening is mainly ablib. The theme is a wild west theme. So I would like someone to be enthusiastic and be able to encourage group participation and dress for the part. The evening will be held in a hotel in central adelaide. Wage is negotiable. We have only a small group about 25 people who have a good sense of fun
