How to make a Safe Deals service on WordPress for individuals. goods?

Question

Payment systems

How do I implement a secure transaction through WordPress.

Important , not through another service, but I want to create my own service for secure transactions.

For now, I want to add an option for physical products only. Let's say a person orders a product from a seller, the seller forms a deal. Describes the product and makes a price. He is given a product code. The buyer enters the code and pays for the goods. His funds go to the service. Then, when the goods are delivered and the person receives them, he confirms the transfer of funds and the money that was on the account with the service goes to the seller.

Are there plugins? similar to what I said. If there is, please remove it.
Ps if there are people who can implement this, write, I will pay for this work
