A highlight of many business conventions is the guest speaker presentation. A prominent speaker can attract publicity for your company and help draw additional participants. A speaker who possesses a particular expertise in your industry also can offer valuable insight for your employees. Landing a hot talent or famous personality can also bring greater prestige to your organization. If obtaining the right speaker for your company's conference is your responsibility, make a good impression on the desired guest speaker by sending a professional, informative letter to invite him to participate.
