I need someone with significant Drupal experience to:
(1) Upgrade my Drupal website from 4.7.X to 5.2. There must not be any downtime to my website, and the upgrade must retain my current modules and site design.
(2) Adjust the site so search engines to not see duplicate content. Add the Global Redirect Plugin, and adjust the httaccess and [url removed, login to view] files as necessary.
(3) Install sitemap module.
(4) Fix the search feature on front page.
(5) Install the Page Title module
