Limit Collection Inventory Shopify site linked to Printful

I am looking for an experienced developer proficient in Shopify custom coding to enhance my store's inventory management system. My store is integrated with Printful, and I require unique customization to manage my inventory on a collection basis, instead of the typical item-level control. Check out my site at [login to view URL] The key requirements include: - Developing a feature to limit the total inventory available for an entire collection. - Implementing a system to display a “sold out” message below the product title when the collection's total inventory reaches zero. - Custom script to ensure that once the "sold out" threshold is met, the notification is dynamically added to all relevant product pages within the collection. **Ideal Skills and Experience:** - Proficiency in Shopify platform and its API - Strong background in custom coding for Shopify stores - Experience with inventory management solutions - Familiarity with Printful integration - Ability to implement UI changes for displaying custom text This project requires detailed attention to ensure seamless integration without affecting the existing store setup and user experience. The ideal candidate should have a portfolio demonstrating previous Shopify customization projects and be able to provide insights into potential challenges and solutions related to this task.
