WordPress + APIs Expert

Hi,
We need to implement some changes on the website. You can access it here: http://13.233.250.81/

Changes required:
- Search functionality throughout the website with click functionality (It is done partially)
- List the products in the sections via Apis as per the doc we shared.
- All products page listing by divisions/forms and without division/forms as shown in the doc.
- Design the pages (Homepage, All products page, single product page) according to the doc
- Sorting & Filtration on the products page

Recommended: Please go through the doc thoroughly.

Note: we are focusing on mobile-first design.

Looking for a long-term association if I like the work.

Thanks!
