Modernize Letter.is pages

I need a partial website redesign for https://letter.is. We need to add the design to the pages that are missing and also remove any inconsistencies.

Key Tasks:
- Redesign the Pricing page in a modern style
- Apply consistent design to the following pages:
- Terms and Conditions
- Refund Policy
- Non-USD Pricing Pages

Ideal skills and experience:
- Strong web design portfolio
- Experience with modern design aesthetics
- Attention to detail for consistency across pages
- Familiarity with the platform used for letter.is

Looking forward to your proposals!
