Application of queuing system for custom t-shirts

I'm looking for a freelancer to develop an application for a custom t-shirt queuing system. I need a priority-based system to manage up to 100 orders daily, and it needs to be done as soon as possible. It is essential that the freelancer has experience in developing queuing systems, especially those related to t-shirts or other apparel. My ideal candidate should be able to offer innovative solutions to scale the system as necessary in the future. The application should be user-friendly, secure, and reliable. I'm also open to ideas and suggestions.
