Shopify Store Build Expert Required – Customised & Personalised Products

I am looking for an experienced Shopify Developer/Expert to complete and build a professional e-commerce store focused on customised and personalised products.

The payment gateway and shipping setup are already completed, so I am specifically looking for someone who can focus on the Shopify store design, product customisation functionality, and overall customer experience.

What I Need
Complete Shopify store design and development
Professional, modern and mobile-friendly design
Customised/personalised product functionality
Customers should be able to enter names, text, initials, etc.
Custom product options and fields
Image upload functionality where required
Product personalisation/preview functionality
Live preview of personalised products, if technically possible
Dynamic pricing based on customisation/options where required
Proper product variants and options
Clean and conversion-focused product pages
Collection/category setup
Shopify theme customisation
Custom Liquid/JavaScript development where required
Required Shopify app integration and configuration
Mobile and desktop optimisation
Speed and performance optimisation
Basic SEO-friendly structure
Complete testing before launch
Fix any bugs/issues related to the customisation functionality
Basic guidance/training so I can manage products and orders myself
Already Completed

Payment gateway integration – DONE

Shipping setup – DONE

So these two areas are not part of this project.

Most Important Requirement

This is not a standard Shopify store project.

My main requirement is the ability to sell personalised/customised products, where customers can customise their product before ordering.

For example, customers may need to:

Enter a name
Enter custom text
Select different options
Upload an image/design
Choose colours/styles
See a preview of their customised product
Place the customised product in the cart with all customisation details correctly attached to the order

Experience with Shopify product personalisation apps, custom product builders, Shopify Liquid, JavaScript, metafields and custom options is highly preferred.

Please Include With Your Proposal
Examples of Shopify stores you have built for personalised/customised products.
Links to your previous work.
Which Shopify personalisation/customisation apps or technologies you have used.
Your approach for implementing personalised products.
Estimated project timeline.
Total project cost.
Any recommendations you have for improving the customer personalisation experience.

Please apply only if you have genuine experience with Shopify personalised/customised products.

I am looking for someone who can take ownership of the project and build a professional, user-friendly and reliable Shopify store, not simply install a theme.
