139171 Mailing List System Integratio

We have an existing online system that allows users to sign up for access to video clips through a protected database system. There is an automated system in place for users to sign up for a username and password and operates beautifully. We need to add the following functionality to the online system: Users need to be able to check a box that allows them to sign up to be updated when a new video clip is added to the site. By selecting this box, they need to be added to the mailing list when the sign up form is submitted. We need an online interface to be able to manually send emails to the list whenever there is a new video clip available on the site. IMPORTANT: The list functionality can be achieved using an existing mailing list program or existing code. We are fully comfortable with that. Users need to have the ability to unsubscribe by clicking a link automatically placed at the bottom of each email In the existing ?my account' area, users need to be able to check or uncheck a box which will allow them to subscribe or unsubscribe to the list. The site is developed using ASP and MS Sql as a backend database. We are looking for an experienced programmer who can complete this is a short period of time. Thanks!
