Software Developer to create a VPN connections

We require a software developer to create a Windows (XP, 7 and 8) application that will create a VPN (Virtual Private Network) to a server.

The software must, in general, be able to do the following;
Allow the user to enter a username and password
The software will then automatically create a VPN connection the server (in the background)
The software will start-up by default when the user starts their PC.
The software, once a successful connection has been completed, create new network drives on the users PC to set destinations.

We are looking for an estimate at this stage for proof of concept.

However, the candidate that provides evidence of building Windows applications and is willing to work on this project long term, will be strongly considered when we are to proceed.

Please post any questions about this job onto the clarification board and I will be happy to resolve.

Thank you,
Marc
