If your stuttering doesn't happen on every word then why bother thinking about it and getting debilitated cuz you stutter? When you are presenting, just say what you want to say and if stuttering happens just ignore it cuz it's of no use to dwell on stuttering incidents or anticipations. I don't think your stuttering is that horrible and you can't overcome it in your presentation. Just don't shit in the pants before the presentation and don't get delusive that you can't accomplish your presentation, you will be poked fun at, you will get blocks on the first sound of the script and etc.
