Additions To Drupal Website

Our web developer disappeared halfway through a project for a series of (virtually identical) landing pages on our existing Drupal website. Most of the work is already done. Key elements remaining are: 1. Formatting changes (including some dynamic insertions); 2. Setting up system so that people can invite friends through their webmail; 3. Ensuring all submissions report to the database; 4. Duplicating some of the pages in a different (very simple) design format; 5. Putting in code so that all pages can be tracked by Google Analytics; 6. Fixing an error message; 7. Fixing some of the site navigation; 8. Help us integrate an autoresponder (probably Aweber) with our website submission process; and 9. creating a redirect for another url. See full brief attached. Please state: a. your quote; and b. expected timeframe.
