You will have to make up for your speech shortcoming with the rest of your presentation. Work on fixing everything you have actual control over. Weight, physique, how you dress, finances etc. I can tell you from experience that once you level-up all these other areas of yourself that the stutter will bother you a lot less. It worked for me. I'm young (ish), semi wealthy, in great shape with an impeccable wardrobe. Honestly I'm so far ahead of my peers in all those aspects now that the stutter hardly brings me down.
