Browser extension for VPN Provider (Proxy)

Hello, This project should be pretty simple for someone who has already implement similar projects. We need a browser extension for Chrome (Opera), Firefox and IE (Edge) that allows the user to sign up for our service (link to a web page) or login (using a username and pass) if the user is existing. After the successful login (API call into our system) a list of location will be loaded (also received from our API) and the user will be able to click on a location and a proxy from that location is set as active in the browser. A zone of announcements / news is also required to be implemented. The content is also retrieved from the API. This project will have 3 phases: - The current phase that is described here - The second phase that will include fine tuning for the extension (like design / additional small features) - The third phase that will include adding a major feature We are looking for developers with experience in building browser extensions (if you can show your work in the bid – we will review it) that are able to deliver this project in time. As reference you can consider the extensions developed for TunnelBear, Hot Spot Shield, Hola or Betternet. We are looking forward for your bids. Thank you.
