UI/UX Designer : Transform UX Wireframe/Mockup to Good Looking UI Design

I have a set of UX wireframe/mockup for website and mobile app. I want a professional UI/UX designer to transform it into good looking UI design for desktop, tablet, and mobile screens so that the developer could develop the frontend based on that UI design.

Showcase of your previous mobile app & website designs would be appreciated.

Let me know your quote.
