WordPress Store Checkout Overhaul

I need to enhance my WordPress store's checkout process. The current design is blocky and non-professional, and I want to improve the user flow for a more seamless shopping experience. It is a very small site with just a few pages but I'm struggling setting up WooCommerce to function correctly i.e. sending emails.

Key Requirements:
- Redesign checkout for a professional look
- Enhance user flow to minimize cart abandonment

Ideal Skills:
- WordPress development expertise
- Strong UI/UX design background
- Experience with eCommerce checkout optimization

Please provide examples of previous work.
