We need you to find the CHEAPEST offer of 'GIGABYTE GeForce GTX 1080 Ti Aorus Xtreme Edition 11 Gb' video cards in China among the companies that can organize shipping to Russia (St. Petersburg) and find out payment terms and delivery time. We need 6 video cards. As the result we should get a report in the form of: Company names, contact details, price for 6 video cards in USD, payment terms, delivery terms and time. Once we select the company from the list we might ask you to assist us in communicating with the company. So, payment for the project will be done in 2 parts: 1. once we receive the list of companies and check it (15 USD) 2. once we have successfully placed the order with some of those companies (10 USD)
