Car Parts Search Extension for 3 Webshops

I would like to create a website and an associated Chrome extension that allows users to search for car parts through a central search filter across 3 different webshops. One of the webshops has a robot verification system that checks the user by describing characters. The extension must automatically fill in the search filters on the appropriate webshops based on the central search filter. Additionally, the search filter should be embeddable into a WordPress site. The central search filter must be very user-friendly and aesthetically pleasing, adorned with car emblems, icons, and other visual elements.

Main Features:

Central Search Filter: An aesthetically crafted, user-friendly website or WordPress widget where users can specify their car part search criteria. The filter includes car emblems, icons, and other visual elements for easy and intuitive use.

Chrome Extension: The extension must be able to automatically fill in the search filters of the given webshops based on the central search filter. It should also be able to handle the robot verification in one of the webshops.

Search Initiation on a New Tab: When a user initiates a search, the 3 webshops should open in new tabs with the appropriate search filters.

WordPress Integration: The central search filter should be integrable into a WordPress site as a widget or shortcode.

Data Synchronization: The extension must be able to synchronize different search filters and fill them based on the central search filter.

Requirements:

Experience in web development, creating WordPress plugins, and developing Chrome extensions.
Good knowledge of JavaScript, HTML, CSS, and WordPress APIs.
Ability to create visually appealing and user-friendly interfaces.
Attention to detail and quality work.
Communication skills and provision of regular project updates.
Optional:
