Help with Itabag?

Hello! I have an idea for a one off ita backpack, that I've been mulling over but have no idea about getting it made. It's just a single design for personal use, and it's based off a snail shell. I have zero clue about where to find someone who could make my custom bag or if my design would even want work somewhat as this is my first time trying to design a personal bag. Any help would be appreciated! X 😄
