We need an experienced sysadmin to help us with the following:* Provide initial consultancy on a preferable solution to choose, and make recommendations of which software to use.* Optionally assist with parts of or complete setup of backend solution (No web GUI coding needed)* Optionally provide further support/consultancy later on.

Requirements for the solution:* Open source software is preferred* Lightweight and portable. Easy to setup on a standard Linux server, easy to setup on a VPS.* Scalable as user base increases (to hundreds of thousands of users)* User friendliness for end-user. Must provide simple setup for non technical end-users* Authentication in some way. Either through browser, or by logging in to separate web GUI that adds/writes the users IP to a whitelist/config file.* Keeping bandwidth usage low. If possible minimize the content that has to pass through the service.
