We have a Drupal site that needs a Drupal guru to add some features to it.
1) Facebook login
2) Customized comments area (css styling)
3) dynamic sidebars according to the content - we would like the sidebar to change according to main content of the page. (for example, if an author has 10 publications, then every time one of the publication page appears, the author's short bio will automatically appear as one of the sidebar without us defining it manually)
4) modify couple content types
Please bid if you are an experienced Drupal guru and can quickly implement these tasks starting this weekend. Thanks.
