Hi there! I'd be keen to work on this project and can start immediately.
It's been a few years since I've used Joomla specifically but I have much experience with CRMs and CMSs in general. In particular (if you refer to my Freelancer reviews), the work I did for the user "outsourcem" on the project "Content Curated Needed" was to create articles using Wordpress, and all the work for user "gencirculus" required using EDUonGo, a popular LMS (Learning Management System). I also have a year's experience using Drupal (not on Freelancer, though). Therefore, quickly getting up to speed with Joomla again will not be a problem as I already understand the essentials.
I also have a background in Systems- and Database Administration so I might look into generating a SQL script to quickly populate your database depending on whether and in what format it'd be possible to obtain the info from your competitor's website.
Furthermore, I've used automation tools like iMacros, AutoIt and AutoHotkey for data entry work on websites which might also come in handy.
Thanks for your consideration. Feel free to message me should you wish to discuss further details.
Kind regards,
Richard Herselman
