Hi, it's my job!
I have been doing Drupal site development for a very long time. I can fix all these 404 errors on your Drupal sites. Please message me to discuss the project right away.
My bio: I'm a Drupal themer/developer, I have over 6 years working on various Drupal (D6-D7-D8) projects from theming (Design, HTML, CSS, Javascript) to development (PHP, MYSQL, Drupal). I can create new themes and new modules, fix theme issues and module issues, create and upgrade Drupal sites, also suggest the best solution for Drupal site owners.
