I'm looking for a skilled WordPress developer to create a modern, clean single page site for me. The site will be primarily static with an added functionality for users to purchase airtime. An API for this function already exists and will be provided.

Key Requirements:
- Proficient in WordPress with a strong portfolio of modern, clean site designs
- Ability to implement API for airtime purchases
- Experience with building static sites with dynamic functions

Design Style:
- The site should embody a modern and clean aesthetic

Color Scheme:
- A specific color scheme hasn't been defined yet, so a keen eye for design and color will be necessary to create an appealing site.
