Implement Navigation Structure WordpressWoocommerce website

Description

We require someone to implement a robust navigation structure on a new wordpress website currently being developed with Astra/woo-commerce.
The store will hold upward of 2500 products spread across multiple woo-commerce product categories. Some categories have a large number of sub categories so experience with category landing pages is a must. Navigation will be require dynamic filtering and search capabilities where necessary.
We have already created a draft navigation structure which is attached (see attached pdf) and require an experienced wordpress/woo-commerce developer to advise on the suitability of this structure, make modifications and improvements where necessary and implement the navigation structure to the website. Navigation structure must offer ease of use for customers and be fully SEO compliant.
We have our own 'in house' design team that at the direction of the developer we choose to work with will handle any digital design elements required for the navigation.
We would prefer a fixed cost but also happy to consider suitable freelancers who can offer project at an hourly rate with a well considered total cost indication
