Desktop application to provide 5 concurrent connections via VPN

Please read in full as this project is in several parts. I would like a website developing with the following functionality: It will be a website that has paid subscribers. The users will create an account and sign up to a monthly subscription using a payment gateway. The function of the website is this; It enables a user to connect to a particular website using up to five separate accounts at the same time. Each connection must be routed via a VPN. For example if an Amazon seller (the site is not Amazon, I am just using that as an example) has five separate selling accounts, they must currently log in to each selling account at a time. This is time consuming. Using my service they would be logged into all (up to 5) accounts at the same time. Please look at the attached image, this is just to explain how the system works and is not a final design image. The user logs into my service and they will see up to 5 tabs on the website. Each one of their accounts will be on a tab. All accounts will be logged in at the same time and the user simply clicks on a tab to use the corresponding account. Each of the accounts will be logged in using a different IP address. The IP addresses must never ever cross the accounts. For example, if Account 1 has in the past logged in to 123.456.789 then none of the other accounts can ever use that IP address. This project comes in parts. The first part of the project is to prove that you can create a simple desktop application that has 5 tabs that connect to the internet with each tab connecting to a different ip address. Once this has been proven we can then develop the site as per my requirements. Please make your bid JUST for the desktop application that looks similar to the attached image apart from each tab is a web browser that has a concurrent connection each using a different IP address. Please ask any questions you may have. I have set the budget to £10, please ignore this, just bid what you would want to complete the first part of this project as explained. Thank you for looking.
