Hi, it's my job!
I have been doing Drupal site development for a very long time. I can convert your Joomla 3 template to Drupal 7 theme in 24 hours. Please message me the link to your Joomla template to discuss the project details 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.
Thanks,
Hoa
