Prestashop-to-Shopify Migration

I need my entire online store moved from Prestashop to Shopify while keeping the current look and feel intact. The migration must include every product, all customer data, and the full order history so I can pick up business on Shopify without missing a beat. Beyond the straight transfer, I will also require a few custom functionalities or apps added on Shopify to replicate features I rely on now and streamline operations going forward. Deliverables • Complete data migration: products, customer records, order history • Theme ported over so the design remains identical in layout, colors, and branding • Installation / setup of agreed-upon custom apps or small coded tweaks, tested and working on the new platform • Final QA to confirm URLs, images, inventory counts, customer accounts, and past orders display correctly Please let me know your approach, any migration tools or scripts you plan to use, and an estimated timeline to get the Shopify store live.
