A Few Queations

hello friends, I have a project that I am working on as a young person. I want to make computer equipment and parts, especially peripherals (keyboard mouse etc) a more organized and secure global marketplace, as well as normal users (individuals) and large companies to return products or repair products. I want to ensure that it re-adds to the market and faster, it will be a much better choice, especially for countries with bad economies, what kind of features do you want from you? How should I talk to companies about this issue, I am planning to contact companies such as Amazon and equipment manufacturers (Logitech, Razer, SS).
