☆★ Create a custom Shopify page ★☆

We have several webshops [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] and we want people that access [login to view URL] to land on a separate page that will allow them to select the country. We can host this page on Shopify, as a separate page (like a blog or something), OR we can host [login to view URL] on [login to view URL] and have a popup. See these two examples: [login to view URL] (popup) [login to view URL] (page) To qualify for the job (and to make sure you read the description) please answer these 3 questions: 1. What is 5 + 9? 2. How do you intend to do this? 3. Have you done anything similar? Can you show an example?
