I need you to put together a startup pitch on my product, design is not paramount, the most important thing is a logical narrative

I'm looking for someone to help me with my startup pitch! My product is a digital product, and I need my pitch to be more than 10 minutes long. The main goal of my pitch is to gain customer interest, and while design does matter, the primary objective is for it to have a logical narrative. I'm hoping to find the perfect person who can help draw interest to my product, while also ensuring it has a strong narrative.
