Creating a P2P online marketplace with auction from scratch (incompleted figma available)

Help is needed to create a P2P online marketplace with both auctions and sales functions for users to list their products on the platform. The end product/platform would be very similar to eBay.

Looking for talents that could help me with the:
- UIUX for user journey, gamification, etc
- Front-end development
- Back-end development
Fullstack preferred

Currently, I only have an incomplete figma draft.
