PHP/Laravel/MySQL – Marketplace Development

No hourly bidders.
Do not list and expect me to go through your portfolio now. I hate.
Custom bids only.
I need speed. Design in 3 days and Develop in 15 days so if you are solo freelancer, you will waste time as I know you won’t be able to do in 15 days despite you are expert/senior.

Put as many resources as you need to develop this.
I will share my website once you show me your 3 marketplace with excellent design.

This project should be called seller portal cum marketplace.

Design will be yours so if you can not impress me with design/UI/UX -don’t ask me – will be useless.
Seller Portal part will let sellers upload a product, discounts, get reports and all from backend.
Marketplace will let buyers buy from product catalog/ product details page. We will not collect payment though so no need for payment gateway. Instead we will integrate my own chatbot (javascript) in product details page.
We will use my own APIs to push/pull data for showing in this site.
Count 15 Main pages/ features for development and 10 APIs to integrate (push/pull).

I have same marketplace / features with a bad design/UI/UX
