Redesign WooCommerce cart and checkout

I’m looking for someone to redesign my WordPress (WooCommerce) cart and checkout pages. At the moment, the design is very basic and simple. I’d like it to look professional and well-structured.

I don’t have any design references, so you’ll need to come up with a clean, user-friendly design on your own and share it with me for approval.

The checkout page currently includes some custom snippets for additional functionalities, so your redesign must not affect or break those features in any way.

Requirements:
- Redesign cart and checkout pages with a professional look (must be responsive).
- Ensure existing custom functionalities remain fully functional
- Deliver within 2–3 days max
