Hiring UI/UX Designer for WooCommerce Typography & Spacing Improvements

I run the WooCommerce site yourgetbarter.com and the theme is staying exactly as it is — layout, colors, and fonts should NOT change.
However, the text currently feels cramped. I need a UI/UX designer who understands typography and can improve line spacing and overall readability across the entire site.

What I Need
- Improve global line spacing and paragraph spacing
- Adjust vertical rhythm so product descriptions, paragraphs, and checkout messages feel natural and readable
- Make sure spacing looks balanced on both desktop and mobile
- Apply changes either through theme settings or clean child-theme CSS (whichever is smarter)
- Document every change clearly so I can reapply them after theme updates

Important Requirements
- No layout, color, or font changes
- Only typography and spacing cleanup
- Must be comfortable working with WooCommerce themes and CSS overrides
- You should have previous experience refining readability and UI spacing in e-commerce sites

What I Will Provide
- Access to wp-admin
- A staging copy for safe testing
- Clear guidance on areas that feel most cramped

If you've handled similar UI/UX typography fixes before and can deliver clean, documented improvements quickly, I'd like to hear from you.
