Upgrade Joomla 3 to Joomla 4

I need a Joomla developer who can upgrade my current Joomla 3 website to Joomla 4. I have a backup of my website so the developer can start the upgrade process without delay. The developers must have high-speed internet and be able to create a copy of our site and database on their server to perform the upgrade first so any issues can be worked out before updating our live site. Our site and database are very large so you should be able to handle large downloads. However, there are custom extensions and templates that need to be updated for Joomla 4 compatibility. The ideal candidate must have experience upgrading Joomla websites and be familiar with custom extensions and templates. The upgrade should be completed within 1 month.

You must be able to communicate in English and be willing to give daily updates on the progress.
