Wix Wall Art Customization Tool

Build a Custom Wall Art & Frame Configurator for My Existing Wix Website
I am a professional landscape and wildlife photographer based in Kakadu, Australia. I already have an existing Wix website for my photography business and I am looking for an experienced Wix Velo developer to build a custom wall art configurator.
I do not want my website rebuilt. I only want this configurator added to my existing Wix website.
The configurator must allow customers to:
Select print size.
Select frame colour (Black, White, Oak, Walnut and other colours).
Select mat options (if applicable).
See the frame and mat change around the image in real time.
Display the finished framed size.
Automatically update the price when options are changed.
Add the configured product to the Wix shopping cart.
Work correctly on desktop, tablet and mobile devices.
Requirements
Must be built using Wix Velo.
Must integrate with my existing Wix website and Wix Store.
The design should be modern, clean and easy for customers to use.
The preview should look realistic and professional, similar to high-end photography print websites.
Future Updates
It is very important that I can easily update the configurator myself in the future.
I need to be able to:
Add or remove frame colours.
Add new print sizes.
Update prices.
Add or remove mat options.
I do not want to pay a developer every time I need to make these changes.
Print Supplier
My professional print supplier is BPro (Brilliant Prints Professional). The available print sizes, frame colours and options should be based on the products they supply.

My budget is limited, so I am looking for a cost-effective solution rather than a complete website rebuild.
