WordPress/WooCommerce Specialist Needed: Fix Cart/Cache Issues & Server Migration

I am looking for an experienced WordPress developer to help resolve persistent issues with my WooCommerce store and manage a server migration. Current Issues: 1)Shopping Cart Functionality: My WooCommerce site has a critical issue where the shopping cart appears empty on mobile devices, even after products are added. This seems to be related to cache conflicts between our hosting environment (SiteGround Dynamic Cache) and our caching plugins (WP-Optimize). We need someone who can correctly configure the caching rules to ensure dynamic WooCommerce pages (cart, checkout, my-account) are properly excluded from cache. 2)Server Migration: I am looking to reduce operating costs and would like to migrate my current WordPress site from SiteGround to a more cost-effective hosting provider. I need a seamless transition with minimal to no downtime, ensuring all database, email, and SSL configurations are correctly transferred. website https://booksunion.com/?v=3d9975706be3
