Italian Language Zencart 1.8+database 1.5.1 replacement

I am looking for a freelancer to help me migrate my existing e-commerce platform, currently running on zencart 1.8 with a volume of customer data in database 1.5.1, to a different platform. Ideally, I would like to move to Magento, Wordpress Woocommerce or Shopify, but I am open to alternate suggestions. Most importantly, I need the migration and any associated customizations to be professionally undertaken as my business relies heavily on my e-commerce platform. The new platform must provide a smooth and efficient transition from the old website, with minimal interruption in customer service. I also require the new platform to take full advantage of the current database version (1.5) and customization of the new e-commerce platform is essential for us to move forward.
