Social Media App

We are looking to have an app developed which works with Facebook and Twitter. The app will consist of an admin area and main screen. The main screen will be accessible to all. The admin will require login. The front page will show tweets which mention a specific twitter account and/or use a specific hastag. The hashtag and twitter ID will be configurable through the admin. The front page also needs to be able to bring in posts made by a specific page on Facebook. These will ONLY be the posts made by the page itself and do not require to show comments or mentions from others. We also need to be able to show list of profile pictures which have tweeted. The admin will also need to be able to remove tweets from the wall and also run all tweets through a filter of bad words before they get posted on the front page. The list of bad words will also need to be fully manageable via the admin - able to add/edit/remove words from the DB. This will need to be able to run on all latest browsers. It is important that the script is light and can easily work on a shared server. We are looking for a long term relationship as new features and changes will be required all times.
