Microsoft Store (free) VPN App

Hello, We want to create a free VPN app for the Microsoft Store. We have the same app present in Google Play and Apple Store and it is pretty simple: makes an HTTP request in order to get a list of servers, shows the servers (and flags of the country) into a dropdown, the user selects a server and press Connect. For the Microsoft Store app – the VPN connection will be IKE v2 – using a username and pass that we will provide. The application is very simple and a developer with experience in building Microsoft Store app should be able to complete it in a short time. In order to see how a similar app looks and works, start Microsoft Store, search touchvpn (it is a free – upgradable app) and see how it look and how it works. If you have questions please ask. If you can show us Microsoft Store apps that you have developed – we will happy to check them out. We are looking forward to your time/cost estimation for this project. Thank you!
